Board: GumStix Connex PXA255
RTEMS BSP: gumstix
Flash: http://www.gumstix.net/feeds/u-boot/
+ Fetch a connex U-Boot Flash image
dd of=connext-flash.img bs=128k count=128 if=/dev/zero
dd of=connext-flash.img bs=128k conv=notrunc if=UBOOT-FLASH-IMAGE
dd of=connext-flash.img bs=128k conv=notrunc if=UBOOT-FLASH-IMAGE
+ We would like to do more preprocessing but for now, just copy
the UBOOT-FLASH-IMAGE to ${HOME}/qemu. The one in this directory
works fine.
+ This flash is configured to boot GNU/Linux. There is no kernel in
this flash image and we want it to autoboot an RTEMS application.
So by hand, we we would LIKE TO BE ABLE TO boot it, reconfigure
the bootcmd. BUT THIS DOES NOT WORK!!!
GUM> setenv bootcmd = bootelf 0x400000
GUM> saveenv
Saving Environment to Flash...
...
+ Then exit and the flash.img is modified.
So we rebuild the flash image booted each time
