Unable to Program the Attached HEX file using UniFlash Version: 2.2.0.00016 for FLEE ECC Area in Corona

Hello QJ,

You are not programming the ECC Area of FLEE [Bank 7] in the HEX File.

That's why it is working for you.

Please let me know if you need any more information.

Are you able to program the attached HEX file from me?

Thank you.

Hi Pashan,

Got an error:

WARNING >> CortexR4: Loader: One or more sections of your program falls into a memory region that is not writable.  These regions will not actually be written to the target. Check your linker configuration and/or memory map.

Your hex is not motorola format, right?

Hello QJ,

I think nowECC is generating wrong address range for ECC of BANK 7.

Can you please tell me ECC Address Range of BANK 7 for all sectors for TMS570LS0432 device?

That will help me find the real BUG with nowECC tool.

Thank you.

Hello QJ,

I am attaching Motorola HEX File for you to try.

    Programming from 0xF0100600 to 0xF01006FF   --- ECC of Bank 7 Section 3
    Programming from 0xF0203000 to 0xF02037FF   --- DATA of Bank 7 Section 3
    Verify from 0xF0100600 to 0xF01006FF   --- Fails

The address range is correct in the attached file.

Please let me know once you try this fail and the reason for failure.

Thank you.

Hi Pashan,

Uniflash can generate/program ECC automatically if check the potion. The Flash ECC is located at 0xF0400000.

For Bank7, data is at 0xF0200000, and ECC is at 0xF0100000. ECC size is data size/8.

Hello QJ,

You didn't tell what is wrong with the attached file dbcBootGMLAN_fee_parity.zip.

That address range is correct for TMS570LS0432 device but Uniflash is not programming the file.

Did it program/verify successfully for you?

Please confirm.
Thank you.

Hi Pashan,

I removed your ECC, and programmed the remaining hex to 0xF0203000. The Uniflash generated ECC and programmed the ECC to 0xF0100600 without any problem. I compared your ECC and the ECC generated by Uniflash. They are different. The correct ECC data is enclosed:

Hello QJ,

Can you please tell me your nowECC version number as well as the command line options used for generating the ECC values?

I used nowECC  v2.21.00    from 14-June-2013

Thank you.

Hi Pashan,

I didn't use norECC. For uniflash, you don't need to provide ECC. Uniflash will generate ECC based on your Flash Data, and program the ECC after programming the data.

Hello QJ,

I want to program ECC based on the user input file contents and not autogenerated uisng UNIFLASH.

How to do that?

Thank you.
Regards
Pashan

Hello QJ,

The attached file with ECC is programming correctly with UNIFLASH for TMS570LS0432 device.

But the file attached before is failing.

Something is wrong with my understanding. Definitely ECC is correct in both the files because nowECC generated the contents.

Please help.

Thank you.
