Hello,
Has anybody been able to successfully single step through U-boot code on an MPC8349 CPU using a BDI-2000?
I've attached two config files. One can be used to flash the 9349E-mITX, and the other can be used to debug it.
The flash-enabled one programs a bunch of registers that wake up the flash chip. Unfortunately, when using this config, U-boot hangs somewhere in start.S. I'm probably programming the board just differently enough to confuse U-Boot.
The other config programs nothing, which gives U-Boot a clean slate to program.
The config I use to debug is much like your second one. In general, less is more.
I presume it should be possible to create a "unified" config that works in both situations, but I haven't had the time to try it.
I've never used GDB with the BDI.
I've used it with Linux drivers and it's really very slick. I imagine it would be excellent with U-boot too, if I could get it to work in code other than start.S.
regards, Ben
Have you tried the FAQ "10.1.2. Debugging of U-Boot After Relocation"? http://www.denx.de/wiki/view/DULG/DebuggingUBoot
