led blinking during boot for debug

Hi,
I'm not sure about assembly language.
You can get sample LED blink test code from spectrum digital inc website (CSL code).

Hi Titus S.
thank you Titus . I have a small bootloader to copy the contains from flash to RAM . I want to insert line of code in it to ensure that the boot pass this specific point and move the testing line to ensure that the code executed successfully . simply i want to but a hardware break point during boot to debug the boot loader .

Abdalla,

Which version of CCS are you using? CCSv6 is what I recommend, since it is the latest.

Which boot mode are you using? Similarly, where does your bootloader reside?

Are you trying to test whether the hardware boot is happening correctly or whether your own bootloader code is working? I think it is your own bootloader code but need to ask.

Why not use CCS to debug this? That is why CCS is there, to allow you to test your code with breakpoints and to test things easily.

Hi RandyP
CCS3.3 can i do it with this version

Abdalla,

With the EVM, there is no license fee for using CCSv6. Why would you not upgrade with no cost?

I have not used CCS4.4 for many years. It will likely work.

Which boot mode are you using?

Are you trying to test whether the hardware boot is happening correctly or whether your own bootloader code is working?

RandyP
