Hi,
OK, I’m running out of ideas. I’m working on a CCWi-i.MX53 JSK. What I’m trying to figure out is - as you might have guessed - to flash a WCE image from an USB stick.
Based on
http://www.digi.com/support/kbase/kbaseresultdetl?id=3305
and
http://www.digi.com/support/forum/40385/mx53-jsk-with-windowc-how-boot-new-wce-from-microsd-using-uboot
my best guess is to either just
dboot wce usb 0:1 fat wce-CCXMX53
or setting the U-Boot command like
setenv bootcmd dboot wce usb 0:1 fat wce-CCXMX53
saveenv
reboot
None of the methods works for me. I’m getting:
Unknown command ‘usb’ - try ‘help’
command usb reset failed
I’m using a freshly formatted FAT32 USB stick with only the wce-CCXMX53 file on it, in either of the J10 USB plugs.
Any help will be greatly appreciated. Thanks in advance
