PROCESSOR-SDK-AM437X: Potential bug in SPI NOR Flash Driver

inno

Hello,

I am running the QSPI_BasicExample_idkAM437x_armExampleProject on a Sitara AM437x IDK.I am using the SDK version 6.3.0.106.

It seems that I found a bug in the SPI flash driver when writing data to the NOR flash using the configuration mode of the SPI-driver. I think the code in the red rectangle, which I added myself, is missing in the example (the code that I added is commented in order to keep the example as it is). At this point in the code a 4 address-byte page program should be performed but the wrong command byte is being sent to the Flash device.

Can you please check this and let me know if I am right?

Thanks

Hi Inno,

Thank you for pointing this out. This looks to be an edge case that should include the if statement that you added in your code. I'll send this over to the development team to see about fixing this.

Regards,

Dillon

Hi Dillon,

Did you get already a confirmation from the development team, that the command byte is wrong? And if so, did they agree on the above fix and when will it be available (which SDK version)?

Thanks,

Inno

Hi Inno,

As of now the development team has been notified of this, but this bug has not quite reached the planning phase and so an SDK version has not been chosen yet.

In the meantime though, adding in your if statement for your implementation would be the best immediate solution for now.

Regards,

Dillon

Hi Dillon,

OK, I understand. I am not looking for any new SDK version, I just wonder if the development team looked at it and could confirm my report. Obviously the issue is on their ToDo list but they did not yet checked this.

Thanks anyway for your support and please keep me updated .
