TMS320C5515-EVM - Problem with NAND-Flash

Martin,

Let's first focus on programmer.out, first question is where you get the programmer.out from?

If you get it from Spectrum Digital, then I have confirmed that it only works for eZDSP'sNOR device, not EVM. They have different NOR devices on the board.

Second is for the NAND, on the same programmer.out from Spectrum Digital, I use chip select 4 for NAND. So, it is 141C:\file_name_path

Can you confirm?

Regards.

Steve,

First: I downloaded the programmer.out from Spectrum Digital (file: evm5515_demo.zip). Is there an other programmer.out for the EVM (if yes - where can it be downloaded)?

Second: correct, at the NAND I use chip select 4, so it is 141C:\file_name_path

Thanks

Martin

Martin,

My programmer.out is downloaded from Spectrum Digital's EVM5515 Support Page under the title Demo Software at the bottom:

http://support.spectrumdigital.com/boards/evm5515/revb/

So I think it is same as yours. Does NAND work all the time on your board? I used 141C:\file_name for NAND and it works al the time. Only NOR has issue.

I am testing a new one for Spectrum Digital to update this page. I can send it to you directly when ready.

Regards.

Steve,

yes, that's the same programmer.out.

The NAND worked for month (with the 141C:\file_name), but now I get an error (ERROR in AtaWriteSectorFlushhfilename - see my first posting) if i want to program the NAND. Booting from the NAND works with the last program I downloaded successful, but i can'd download a new one (or even an old one that is tested). 

If your tests are successful I would be glad if you send me the file. 

Thanks,

Martin

Hi Steve,

hi Martin,

May be bad block appeared in your nand flash and that's why chip return fail to each page program operation.

Martin, you may use other boot device, e.g. NOR flash, burning operation is also simple, check bootloader user guide. 

Steve, do you know, can programmer.out detect bad blocks in nand flashes?

Max

Hi Max,

i think you are right with the bad block in the NAND.

As I understand i can't use the NOR flash for burning operation, because the programmer.out is only for eZDSP'sNOR device, not for EVM (because of different NOR devices).

Also other boot devices (EEPROM, etc.) are not possible because then according to the device order the NAND is used first and  an old valid boot-image from NAND is used. Only NOR is located before NAND.

Yes, it's a good question for TI employee.

What to do if I want store my boot image in NOR flash on C5515 EVM?

Max

I am testing an updated one with working NOR and will post it here first, then asking Spectrum Digital to update to their support page.

Regards.

Martin,

This site does not allow me to attach the programmer.out. Send me your email so I can try send to you.

Regards.

All,

Thanks to Spectrum's great support. It is updated to their support page:

http://support.spectrumdigital.com/boards/evm5515/revb/

Please download from here.

Hi Steve,

do I have to change the settings in my hex55.exe for programming the NOR-flash?

At NAND it was: hex55 -boot -v5505 -serial8 -b filename.out -o filename.bin

With this settings neither the old nor the new programmer.out did work.

Regards

Martin

Martin,

hex55 -i filename.out -o filename.bin -boot -v5505 -b -serial8

should work for both NAND & NOR. The only thing I caught in your msg is the missing "-i" infront of filename.out.

Can you repeat what used to work?

Regards.

Hi Steve,

these settings don't work with my board's NOR.

Is it possible that the new programmer.out downloaded from SpectrumDigital is the same than the old one? I tried to check it and couldn't find a difference. 

Another possibility is that my board has been damaged. I will get a new one in the next days and try it with this one too.

Regards

Martin

Martin,

I will download it to check it out.

Regards.

Martin,

I verified that it works. Please try with a new board.

Regards.

Martin,

I verified the download copy from Spectrum Digital site works. You might have a bad board.

Regards.

Hi Steve!

You are right, it was a bad board. I tested my NAND-bootloader with a new board and it works. 

Now I want to test my NOR-bootloader. But here appears a new question: is it possible to erase the NOR-Flash after the test, because later I want to use the NAND-bootloader again (if yes, how)?

Regards

Martin
