Hi!
I'm trying to debug u-boot 1.1.1 using a EPI Majic JTAG probe for arm processors on an PXA255.
I load the compiled elf-binary down using the JTAG, and try to run it. I get immediately a "Hardware instruction breakpoint" message. Other binaries run without problems using the JTAG. Also when i flash u-boot it works.
Has anyone of you used a EPI Majic to debug u-boot successfully?
Here are the logs:
