Does anyone have a BDI2000 configuration for the P2020DS that they could share with me?
Abatron ships a p2020ds.cfg with their firmware for the BDI. Do you think this is not working or not good enough?
It says, right at the top:
; The values used to configure the memory controller ; are the ones U-boot uses to setup my system. ; Your system may need different ones !!! ; ; This configuration is not usable for U-boot debugging. ; Use it to debug example code loaded into SDRAM.
I'm hoping for a configuration that can program the flash on a bricked board. Then I can flash anything I want without fear of rendering an expensive board useless.
The documentation Freescale sent me claims that U-Boot is in a 4MB SPI flash, however, the U-Boot that came with the board is unable to initialize the SPI subsystem per their instructions.

I thought I'd use the BDI2000 to dump a copy of their U-Boot before I replace it with my own, just for good measure.
Well, if it's really in SPI flash, then the BDI will not help you to dump it. The BDI cannot access SPI flash directly.
Thanks for the information. Ira
