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. |
