I have an AT91SAM9261-EK.

I have compiled the startup project that makes lights flash and debugs to the serial port. Using SAM-BA, I enabled SDRAM, uploaded my SDRAM bin into SDRAM at 0x20000000, and typed go 0x20000000, and the app starts.

Now I want it to start automatically:

1) I close jumper J21 on 1-2 for DataFlash access
2) enable DataFlash on SPI0 CSO
3) send boot file (dataflash_at91sam9261ek.bin from the at91-bootstrap CD) to DataFlash
4) upload my NORFLASH bin to DataFlash address 0x8400
5) close SAM-BA, press RESET, the terminal pops up with RomBoot, the EK is no longer recognized, nothing else happens.

I think the EK is no longer recognized because my boot file is got to before SAM-BOOT starts.

Why doesn't my app start?

Thanks for taking the time to read this sub-newbie question.

It's OK - I worked it out.
