Re: Gumstix Overo boot

Hi Sir,

could you please provide us a little "howto" to put the kernel and userland on a microSD please ?
i guess we need as the verdex to format the microSD with 2 partitions :
- 1 FAT16 at the start
- 1 EXT3 after
then use mkimage (from where ?) to adapt the netbsd kernel to the overo ?

thanks for the help

Hi! all

My Gumstix Overo Fire boots with Chestnut43(expansion board).
Overo works by same OMAP35xx as BeagleBoard.  Moreover, a lot of
expansion-boards exist like Gumstix.
(expansion-boards and Bluetooth, Wifi, MicroSD not support yet ;-)


My Overo patch:

## Starting application at 0x80200000 ...
not specified 'busheader=' in the boot args.

NetBSD/evbarm (overo) booting ...

I will merge this patch in a few days.
