Hi, I'm a new at TMS320F28335 .
I tried to experiment for MicroC/OS II in my F28335.
I downloaded MicroC/OS from my co-worker and apply it to F28335 using CCS.
everything was OK at that time.
But After I modified app.c file in MicroC/OS that I added JUST A ONE task to , The Machine hasn't work anymore (even hello.c)
I killed three F28335 in the same way.
Please help me . I hope to revive it.
----Added task----

Hi, Manoj Santha Mohan
Sorry for late
1) yes.
2) yes. I can tell you steps what I did
1] just downloaded the Micro/OS Program for F28335
2] clicked "import CCS Projects"
3] loaded the OS
4] edited Micro/OS code added 1 task. I haven't mentioned that I edited F28335_Link.cmd too. I changed F28335_Link.cmd to F28335_Flash_Link.cmd
5] clicked Debug
6] All of the program doesn't work.
There are two kinds of error.
first error] When I don't use a flash memory. (It looks like working, but it's not worked. Console has to say "Hello World!")
second error] When I use Flash memory (Load Program error)
edited F28335_Link.cmd

3) No, It's not protected.
I already tried Depletion Recovery with UniFlash, but Console said to me "Error when performing depletion recovery". and also 'Erase Flash' didn't work.
I don't know which program made the chip broke. (Edited Micro/COs or Edited F28335_Link.cmd )
Thank you for your Comment. It's will be a great hope for me.
Manoj,
Here are two error messages below. First one is when I clicked the depletion button. Another one is when I clicked the erase button.
Thank you for your help
1. Yes , I chose V2 when using UniFlash . and actually I'd also used v2 when I edited code using CCS. The screenshot was wrong because at that time, I debug the code in another computer that using v1 configuration. (v2 configuration also made error)
2. I think I can read this area.
0x300000
0x310000
0x320000
0x33FFF8 - 0x33FFFF
3. yep , I attach them ( depletion error and erase_error) . Thanks in advance
Hi,
I think you might have provided the GUI logs instead of 'Debug Server' logs. I forgot to provide the link in my previous post but please see more information here:
You will need to enable the logging before performing your operation, and disable after; and then retrieve the log in the user folder.
Thanks,
Ricky
Thanks for your comment Manoj
But, I am disappointed to hear that the only option is to replace the part.
we've ordered 4 more F28335 products and they were delivered yesterday.
One of them was broken cause the same software problem.
If there is no option without replacing it, but I need to know why they've were broken at least because we are not afford to buy it more.
Our lab have to finish a project by using F28335 ASAP.
Please, Help me out about this problem. There is only support I am able to ask.
Thanks
Ricky,
Thank you for your attention.
1. yes It works
2.
the value is F9F9. and it was not changed after performing an Erase using the Memory view
I found a weird situation when I turned on it .
When I turned on broken device, It shine with red flash without yellow flash. (you can see 00:13~00:14)
Always Thank you for your help
Junsu,
Can you try setting the boot mode to Check Boot Mode:
Use the SW2 dip switch on the controlCARD to configure GPIO84 - GPIO87:
You can verify the bootmode settings by measuring the F2833x Boot Header voltages on the docking station:
