TMDS64EVM: Flash Driver api(Flase_eraseSector) is not working correctly.

Hi Valbhav

I marked resolved my issue but actually it is not completely resolved.

I tested with ospi_flash_io sample application.

This is the sequence of the function call.

Flash_offsetToSectorPage(gFlashHandle[CONFIG_FLASH0], offset, &sector, &page);
status = Flash_eraseSector(gFlashHandle[CONFIG_FLASH0], sector);

status = Flash_write(gFlashHandle[CONFIG_FLASH0], offset, gOspiTxBuf, APP_OSPI_DATA_SIZE);

Also I defined the offset address as 0x03FE0000

When I ran this application 1st time, I can see "All tests have passed!!"

And power off board and turn it back and run 2nd times, application is hanging for ever inside Flash_eraseSector function.

Then power off bard and ran it 3rd time, I can see "All tests have passed!!"

Test result is alternating. Odd time, pass, and Even times it's hanging for ever.

What part should I take a look at it?

Please let me know if you have any suspicious part.

Thanks,

Sangjoon

Hi,

I did not get to see this behaviour at my TI EVM setup, so I cannot comment without knowing few values.

So I would need you to share me the value of the following statements in working and non working case:

You can find this defined in the detailed steps I asked you to implement. It is mentioned in one of my responses above for S28HS512T.

Please write: 

#include <kernel/dpl/DebugP.h>

at the top of the file flash_nor_ospi.c to make sure the logging statements are output to the console.

 I am also assuming that you are rebuilding the libraries before rebuilding your application to make sure the changes in flash_nor_ospi.c is incorporated and taken into account.

APP_OSPI_DATA_SIZE

I am assuming this is 2048 bytes?

I have one more guess on this.

Do you happen to use the ospi_flash_io, but is the following logic still there in your file ospi_flash_io.c ?

offset = APP_OSPI_FLASH_OFFSET_BASE + (flashAttrs->blockSize*2);

This is my first trial's result.

New Value of Configuration Register 1: 6
Value of Configuration Register 2: 11
Value of Configuration Register 3: 0
Value of Configuration Register 4: 168
All tests have passed!!

And below is second result.

[MAIN_Cortex_R5_0_0] New Value of Configuration Register 1: 6
Value of Configuration Register 2: 11
Value of Configuration Register 3: 8
Value of Configuration Register 4: 168

It looks register 3 value is changed from 0 to 8.

Please let me know what part of code do I have to look at?

And the results are coming from below modification. I modified blockSize to sectorSize.

offset = APP_OSPI_FLASH_OFFSET_BASE + (flashAttrs->blockSize*2); to

offset = APP_OSPI_FLASH_OFFSET_BASE + (flashAttrs->sectorSize*2);

and as you mentioned, APP_OSPI_DATA_SIZE is 2048

Thank you
