Hello, I am using 'DULG document'. My work environment in brief: BDI2000, ARM11 based board with flash memory, RedHat Linux-8.0 host machine etc. After compiling the source of u-boot, I got u-boot.bin and u-boot images. Using u-boot.bin image, I reprogrammed flash memory through serial port. Using u-boot image, I started debugging.

I waited for about 20 mintes. No response. I was expecting the breakpoint to hit as explained in 'DULG document' section "10.1.1 Debugging of U-Boot Before Relocation". Please suggest me what could be the problem. I have tested the communication with BDI2000 from the host machine using 'ftp' and 'telnet' commands. It's OK.
Thanks A Lot, Ravi
