Hammer How to Reflash Apex and kernel

These instructions assume that apex has been configured for a 1024k kernel region

Flashing a new kernel (zImage)
You'll find the zImage file in the linux-2.6.22/arch/arm/boot directory.

apex> xr 0x30008000 <=== This is the address that the flash base kernel is copied to by apex on powerup> < send zImage via xmodem> apex> erase nor:256k+1024k apex> copy 0x30008000+1024k nor:256k 1048576 bytes transferred apex> boot 

Flashing a new rootfs
You'll find the rootfs.arm.ext2.gz file in the buildroot/binaries/Hammer directory.

apex> xr 0x30800000 <=== This is the address that the flash base rootfs is copied to by apex on powerup>  apex> erase nor:1280k+1024k apex> copy 0x30800000+1024k nor:1280k 1048576 bytes transferred apex> boot  

Flashing a new bootloader (apex)
apex> xr 0x30008000 < send apex.bin via xmodem> apex> erase nor:0x00+256k  << copy 0x30008000+128k nor:0x00 131072 bytes transferred

then press reset to run the newly flashed apex, do not type boot

Notes on Using Minicom XMODEM
After typing the rx 0x30008000 command in the apex shell running Ctrl+A, S and using xmodem on minicom had to be done quickly. Best bet is to copy the path of the file into a clipboard and paste it. Otherwise type your path as fast as you can. I am not sure why it has this issue, may be an apex timeout on its rx command. Not Sure. But if you encounter that error just retry.
