MMC/SD
about MMC/SD http://www.sandisk.com/oem/manuals.asp

It would be nice to be able to attach a MMC/SD Card to the LaFonera.2100 for bootstrap & storage.

MMC_spi_over_gpio driver for the LaFonera.2100
I develop a specific kernel module for kernel-2.6.26. It handles the card at 300Kbyte/sec.

mmc_spi_over_gpio tristate "mmc_spi_over_gpio MMC/SD card over SPI over GPIO support" Support for driving an MMC/SD card over GPIO pins via SPI.

A beta MMC Driver for kernel 2.6 is now available: It uses gpio bitbanging, the code is currently being reworked a bit to make it look nicer.

* seg fault on hotplug * limit to 512Mb of 2Gb -- quite fixed * issue detecting the total amount of bytes of the MMC -- under fixage
 * Known issues: (version 0.1 for fonera.2100)

Actually (15-02-2009) the driver runs stable, as long as you do not insert or remove the card while the driver is loaded. I am testing a sandisk-2Gb mmc

* [*] BUGS * * it seems there are limit in order to map all the device addresses * encounter a problem with my 2GB SD card: * mmc : MMC/SC * mmc : Card Found * mmc : card in op mode * mmc : SIZE : 231, nMUL : 6, COUNT : 3900, NAME : SD * mmc : Card Initialised * mmc : The inserted card has a capacity of 511.180.800 Bytes * mmc : adding disk * mmc: mmc1 mmc2 * mmc : Card was Found * * 487,5MB and not ~2GB as expected. * concerning large SD card suppport (>= approx. 1GB ) * registers differ a bit on cards with higher capacity. * * fixed to read/write 2Gb with a brute force patch *

MMC/SD pinouts @ http://pinouts.ru/Memory/sdcard_pinout.shtml

mmc-spi adapter
This is a simple SD or MMC adapter card. It allows you to interface with any microcontrollers. It is perfect for mass storage, WAV/MP3 player and data logging. The adapter breaks out the SD/MMC socket to a standard 0.1" 11-pin header. It can be plug directly onto the boardboards. This adapter features innovations that set it apart from other SD card adapter. Innovations feature like on-board card detect LED, Push-Push socket, and 3.3V regulator. Which mean either 3.3V or 5.0V microcontroller can be connected directly with the board. You can even use this 3.3V to power external circuits up to 250mA.



Pinout:

VIN: Input power to the SD card (3.3V to 6.0V) GND: Common (Connects to the housing of the SD socket) 3V3: Output voltage from the on-board 3.3V regulator (250mA) NC: Connect to pin 9 on the SD card (not used in SPI mode) CS: Chip select DI: Serial input data SCK: Serial clock DO: Serial output data IRQ: Interrupt request, connect to pin 8 on the SD card (not used in SPI mode) CD: Card detect (active low) WP: Write protect

Features:

• On-board 3.3V regulator • Connect directly to 3.3V or 5.0V microcontroller • Card detect LED • Include 11-pin male header • Board dimension: 2.0”x1.3”

Hack: Unsolder the caps
In first tests, It's discovered the MMC/SD card is detected, but clk isn't really clear.. So you need to remove the capacitor on the SPI bus (C142, C143, C144, C145) to have clean signals.

MMC/SD card adapter
ebay, search for MMC/SD-USB adapter ... it should cost less than Euro 5, and you could unsolder the card adapter connecor

Hack: MMC/SD card adapter, do it Cheap
you can realize it Cheap from a 5.1/4 floppy cable

http://uanr.com/sdfloppy/ describes how to build a SD card reader from an old 5.25 floppy drive connector.

tiny 48x48 LCD_i2c_over_gpio driver for the LaFonera.2100
This is a gorgeous 132x132 pixel serial color graphic LCD display. It is a small carrier board with Nokia 3210/3310 LCD (be sure it has metallic contacts !!! a lot of newer display has glass contacts )



The driver is under development: actually there is a not a kernel driver but all the stuff is running in user space attached to a minimal gpio kernel support. I mean the user space uses /dev/gpio to handle the display ... anyway it has to be tested and ported in the kernel space with a robust support. Also a text gen is under development and it will be able to generate fonts: so it will be possible to used the lcd this way

less tiny 132x132 color LCD_spi_over_gpio driver for the LaFonera.2100
This is a gorgeous 132x132 pixel serial color graphic LCD display. It is a small carrier board with Nokia 6610 LCD. This inexpensive LCD comes with a powerful software adjustable LED backlight. It uses a simple 3 wires serial SPI 9-bit interface. This is a nice compact color LCD board (1.7" x 2.2"). The very important and unique feature it can interface with 5V or 3.3V logic directly. Since the LCD takes 3.3V logic, there is an on-board logic converter so you can interface 5V microcontroller directly. There is also an on-board boost voltage circuit to drive the LED backlight at approximately 7.0V. You can even vampire a small current to from the boost circuit to power other circuitries. It is breadboard friendly so you can plug directly onto the breadboard. Only 6 connections are needed:




 * VCC (3.3V to 5.5V)
 * GND (supply ground)
 * RESET (LCD reset, active low)
 * SDATA (serial data)
 * SCLK (serial clock)
 * CS (chip select, active low)

Features:


 * LCD Logic: 3.3V or 5.0V
 * LED Backlight : 7V (On-board DC/DC converter)
 * 132x132 pixel
 * 0.1” spacing (breadboard ready)
 * 4,096 Color Display
 * 9-bit SPI
 * Uses the Epson S1D15G00 Controller
 * Connect directly to 3.3V or 5.0V

The driver is under development: actually there is a not a kernel driver but all the stuff is running in user space attached to a minimal gpio kernel support. I mean the user space uses /dev/gpio to handle the display ... anyway it has to be tested and ported in the kernel space with a robust support. Also a text gen is under development and it will be able to generate fonts: so it will be possible to used the lcd this way

writing a framebuffer driver for an embedded spi interface
if you have a small Nokia knock-off LCD board that is currently connected to our embedded system using the spi protocol


 * you have a kernel module that correctly opens up the pins for data transfer, and accepts ioctl commands on /dev/ssplcd
 * you have the ability to set pixels, lines, and send bitmap images to the LCD screen from user land. The LCD has its own controller on board, so we do things like 'set row x, set col y, send RGB' etc.

supposing you also have X server (KDrive or fbdev) installed on the root filesystem (but it is incorrectly configured).

the next should be


 * Figure out how to get a framebuffer device up and running using the LCD board
 * Understand what exactly I need to be looking at - /dev/fb0, vesa, X server, ...?

Any suggestions or pointers would be so helpful. I'm not sure if I'm looking to be writing a new kernel module, or a new framebuffer device, or ...?

From my understanding, as long as I can correctly implement /dev/fb0 (kernel module or other) - then X can talk to this device and be none the wiser

it's under development and valuation (what is the best ? it's better to have a MMC of 300-500Kbyte/sec without any add of specific electronic ... or it's better to have a microdrive of 400Kyte/sec that requires a an electronic add on ??? still dunno =P ): actually there is a hardware shifter attached to the gpio that transplate serial stream into a parallel data. It's so slow and requires a level translator (3V<-->5V)

the kernel drive export his support to the "pATA/CF" level in a polled way: no IRQ support!

idea of how to unsolder and solder http://homepage.ntlworld.com/tenerifeworld/Fonera/Replacing%20the%20memory/

Is it possible to replace the m25p64 flash chip with the m25p128 to double the flash space? Daemondust 04:53, 23 Apr 2007 (CEST) Which type of SDRAM

Hi to all. The original SDRAM chip on the Fonera is a hynix HY57V281620ETP-H which features: 128 Mbit organized as 4 banks x 2 Mbit x 16, 133 MHz An ideal chip needed for the 32MB upgrade may be the hynix HY57V561620ETP-H which is: 256 Mbit organized as 4 banks x 4 Mbit x 16, 133 MHz. Unfortunately is difficult to buy single chips (or small amounts), so we prefer to use PC133 SDRAM modules (like a 512MB PC133 DIMM module - double sided, 8 chips per side - or 256MB PC133 SODIMM module - double sided, 4 chips per side - ). The question is that not all chips from these modules are organized as 4 banks x 4 Mbit x 16. For example, I saw a 512MB PC133 DIMM module with 16 Micron Technology MT48LC32M8A2BB-75 which is organized as 4 banks x 8 Mbit x 8, 133 MHz. Is it possible to do a Fonera RAM upgrade with this chip? (in other words: does the different organization of the same memory size make the difference?)

-> My understanding is that the 4 banks and the x16 is the physical interface to the CPU, so I guess the RAM will need to be of this organization. The "n Mbit" could possibly be increased further, as long as RedBoot is updated to use the additional memory. Kintel 00:54, 19 February 2008 (CET) [edit] Piggy packing 32MB

Hi,

I too thought about extending the Fonera's RAM. However, I would have gone a different route. Since it is quite hard to desolder SMD and you can potentially damage the PCB, I would have tried something like:

- Desoldering or cutting CS# on the original module (in such a way that a wire can still be attached to it) - Piggy packing the 32MB module on top of it, i.e. solder each pin except CS# to the lower chip. - pull high the lower chip's CS# - connect the upper chip's CS# to the PCB

Only thing is I'm not sure that pulling CS# high will actually tri-state the chip's outputs. Maybe you also / instead have to pull CKE low.

just my $0.02 [edit] List of working memory chips

Although I doubt many people have or will complete this modification, I think we should compile a list of working replacements for the original memory chip.

I can hereby confirm that the Micron MT48LC16M16A2-75 (:D) works flawlessly. But, for some reason the modified OpenWRT distribution that the Fonera is shipped with only shows 16 MB. DD-WRT on the other hand shows it all.

- Pinkevin

I can confirm A2V56S40BTP by PSC is workin. Found on a TwinMOS 128MB stick with 4 chips. If someone need one, I have some spares.PM me in the forum.

compcache: have more (compressed) ram or faster (compressed) tmp disk You require kernel 2.6.x to compile these modules. http://code.google.com/p/compcache/wiki/CompilingAndUsing http://code.google.com/p/compcache/downloads/list

1. Checkout the source or download tarball from here. 2. Compile: * run 'make' in directory where you checked-out or untar'ed sources. 3. Usage: * Loading: run 'use_compcache.sh ' to load all required modules and setup swap device. If size is not specified, default size of 25% of RAM is used. * Unloading: run 'unuse_compcache.sh' to unload all modules and turn-off compcache swap device.

If you get any problem using (un)use_compcache scripts, you can do these steps manually as:

* Load kernel modules: o 4 kernel modules are created on compiling. You need to load all three of them (compcache.ko at last) + insmod lzo1x_compress.ko               + insmod lzo1x_decompress.ko                + insmod tlsf.ko                + insmod compcache.ko compcache_size_kbytes=5120 (compcache_size_kbytes param sets maximum size allocated for compressed pages) o device node /dev/ramzswap0 should be automatically created after loading compcache module. If not, then manually create it as: + mknod /dev/ramzswap0 b 253 0 (replace 253 with whatever major no. is assigned to this device: cat /proc/device | grep ramzswap) o Add ramzswap as swap device + swapon /dev/ramzswap0 -p 1 (give this swap device the highest priority). o Verify that ramzswap is active using: cat /proc/swaps. Its should show entry of /dev/ramzswap0.

Now, when system starts swapping, compcache will compress and store these pages in RAM itself! :)

About the status of this project
Actually (15-02-2009) i am able to boot the board with uc-gentoo (-glibc) from the mmc-sd the uc-libc stages are still under development =P and the MMC_over_gpio is still not able to correctly identify the byte amount of a MMC card: it's working with a brutal patch
