Problems when CodeWarrior flash u-boot to P2020RDB-PCA

[baijack]

Hi there.

We accidentally got uboot erasred from our p2020rdb-pca board.

And we got a CodeWarrior USB TAP, so we flash the uboot.bin file to p2020rdb-pca by codewarrior.

We follow the steps in cheatsheet but in the end we got a error as the image below:

It says Core not responding, is there any problem with our board or we dont do it right on software?

Thx.

Hi,

1. What CW version are you using?

2. Did you make a P2020RDB-PC project?

3. Please use the connect target and the default P2020RDB-PC flash programmer target task.

4. Please double-check the DIP SW settings to be according with the ones from README file.

Let me know the results,

Marius

Hi,

Thanks for your reply.

   1. The CW version is 10.3

   2. Yes,we did.

   3. We don't know what do you mean about the "connect target"

   4. We checked the SW settings and reflash the CPLD JED file.

     There seems to have some new problem, the ASLEEP LED is on and we got a new error, display as below:

It seems that p2020 is on sleep mode, how can we wake it up? or there is other reason for this?

Thx again.

Hi,

3. You can make directly the connect target from GUI. Basically, this will only run the tcl initialization file on the target (no application is made/built or downloaded).

4. This is not so good. The ASLEEP led should be ON only during reset operation, just after that this should be OFF. Please try and the attached jed file for CPLD and let me know the results.

Hi,

Thanks for your reply.

3. We did as you showed but still the same error.

4. The jed file you attached can't be flashed, says ' The data file may not be valid for the device selected.'

     The jed file we used before is p1021combo_rev4.1.jed, and that is fine to flash.

So, indeed seems to be a hardware issue regarding your custom board. You can check the steps suggested by Heinz here [1].
