zaurus-akita-Flameman

Note

Apologize for the poor status of this ewiki, I am developing for this board, so the wiki page will be improved and completed as soon as it it will be possible

feel free to contact me (see the contact below) in case you need support.

Introduction

The Target-goal of this page is

  • install uc-gentoo into mmc-sd
  • develop devices
  • make the board able to boot it
  • optimize uc-gentoo for embedded
  • produce a uc-gentoo-uclibc
  • add framebuffer and touch screen support
  • re-target all the project into "tiny PDA"


People you could contact if you need help

  • flameman, i'm currently use this board for a project, email
    • msn daredevil-coder@hotmail.it
    • email flamemaniii@gmail.com
    • irc.nick flameman (channel #edev, #oe, #zaurus)
  • you ... if you want ;-)

About the board

Overview

Sharp has introduced a new model in its Zaurus line of Linux PDAs. The SL-C1000 is similar to the SL-C3000, but without an internal harddrive. As with previous Japan-only Zaurus models, the SL-C1000 will be available with internationalization features from a number of global resellers.

The SL-C1000 is based on a 416MHz Intel PXA270 processor. It boots from 128MB of Flash, and includes 64MB of RAM. The 3.7-inch color VGA touchscreen (640 x 480) supports 65K colors. The keyboard uses a stardard QWERTY layout.

The SL-C1000 includes memory slots for SD/MMC cards, as well as for CompactFlash cards. Additional I/O includes IrDA, USB, and LAN ports. It measures 4.9 x 3.4 x 1 inches (124 x 87 x 25mm), and weighs 10 oz (278 grams).

The board consists of:

  • CPU : pxa2 doc.pdf
  • RAM soldered 128MB
  • LAN USBETH 10/100Mbit/sec
  • UART RS232
  • FLASH ???
  • POWER system=3.3V, feeder={5V DC, ___}, ___ Watt
  • System PCB ___ mm x ___ mm x ___ mm
  • RTC the real time clock chip is provided by the cpu


  • CPU_TYPE PXA2
  • SYSTEM_TYPE ZAURUS-C1000

Sharp CE-170TS is a null modem serial cable for Zaurus. It seems to be actually the only available IOPORT serial cable working with the latest Zauruses. A bit expensive, but voltage does not conform RS-232 standard. It works nicely as a null modem with a standard PC, using a special null modem gender changer it works with a RS-232 hardware modem, but it does not work with mobile phone or GPS client cables.

You will find it (on amazon for example, $50) and it will be indicated "for sl-5500" ... well do not trust it: it will work for your c1000, too =P

i like the idea here, but let me get a few things straight:
1. are you guys trying to use the sharp i/o port's USB port?
2. if not, is this possible?
What about stuart? In case you don;t need SIR.

C-860, kernel 2.4,  irda --> ttyS01

I believe the scoop is a proprientary Sharp's ASIC, so the datasheet most probably never would be published or made public: it is an ASIC but by EPSON GA_SLA50000, that is a gate array and we probably will never know what sharp has putted into it. It is a pity.

Any of BTUART pins can be used as usualy GPIO pins. This is so called alternate GPIO function and is described in intel's datasheet. So when BTUART is disabled all its pins are working as just any other GPIO pins. And BTUART is disabled by default in kernel source.

static void __init corgi_map_io(void)
{
pxa_map_io();
iotable_init(corgi_io_desc);

#if 0
/* This enables the BTUART */
CKEN |= CKEN7_BTUART;
set_GPIO_mode(GPIO42_BTRXD_MD);
set_GPIO_mode(GPIO43_BTTXD_MD);
set_GPIO_mode(GPIO44_BTCTS_MD);
set_GPIO_mode(GPIO45_BTRTS_MD);
#endif

/* setup sleep mode values */
PWER = 0x00000002;
PFER = 0x00000000;
PRER = 0x00000002;
PGSR0 = 0x0158C000;
PGSR1 = 0x00FF0080;
PGSR2 = 0x0001C004;
PCFR |= PCFR_OPDE;
}
