Is it possible to force the i.MX28 to boot with the USB recovery mode before it tries the SSP0?
I think something like
I.mx28 power on --> usb recovery mode --> any mfgtool for update there? ...
(yes) --> update
(no) --> boot from SD(eMMC)
one possible solution I have found is to set at every boot a HW_RTC_PERSISTENT bit to boot at the next boot in usb recovery mode but is there any other way?
