Hi All,
I have a custom board based on the ADI GRG board. I have modified the
redboot source code for the custom board and having a compiled
redboot_RAM.bin. I downloaded the RAM version of redboot to the address
0x1000 and gave go. I am getting some hardware breakpoint.
How do i load redboot thro' JTAG and run from RAM ?. I dont have a working
redboot on FLASH, since its a custom board and i need to debug redboot., I
appreciate any inputs on this.
I am using EPI MAJIC emulator and using the following commands to run
redboot.
1) fr m redboot_ram.bin 0x1000
2) g 0x1000
Then getting hardware instruction breakpoint. I tried the RAM version of
redboot what i got from ADI, in the ADI GRG board without the flashed
redboot. Even here getting the same error.
Thanks
Vanitha
