Hi,
After running U-boot-1.1.1 for some months, I am now trying the last CVS version of Uboot (1.1.2) in my MPC8272ADS board. Now, my available "infrastructure" has also grown, as "daddy" has bought a BDI2000 for me. :-)
I was trying to gain knowledge about the relocation address of Uboot into SDRAM, so i have tried adding the -DDEBUG to DBGFLAGS in config.mk to get all the debug("xxx") messages.
Unfortunately, when I do this, uboot (or the board itself) keeps rebooting all the time, without showing anything through the console.
Using my BDI2000 I can see, in RUN mode, that the board is getting a periodic reset. I have tried to debug the init process in HALT mode, but here I have another problem ... when I reach this instruction form start.S
boot_cold: #if defined(CONFIG_MPC8260ADS) lis r3, CFG_DEFAULT_IMMR@h nop => lwz r4, 0(r3) ...
the board resets itself. This arrives both, when I use the image with -DDEBUG flag, and when I use the image without this flag (which runs OK in the board).
Any idea about those problems?
Thanks
Alex
