SPIF_WritePage corrupting source buffer

[wolfgangbregel]

Hi all,

I experience that SPIF_WritePage function corrupts the source buffer (other write operations will do so aswell).
This is due to the fact that SPIF_WriteFn calls SPIF_TransmitReceive() which in turn sets its rx and tx buffer to source buffer, and by this corrupts the source buffer.
Wouldn't it be better to call a transmit only function here?

Best regards.

Hello. Thanks for your response. I had not this problem. But if you are sure about that, i will use transmit insted of transmitreceive.

Hello,

I'm sure about this, as I tested it on real hardware (Blackpill STM32F411CE + 64Mbit Flash 25Q64JVS).
BTW the same applies to the read functions, where a receive only function would be the better choise.

I'll do some more testing and stress tests and will report if issues arrive.

Thanks for your work and the seemless integration into the STMCube ecosystem.

Best regards,
Wolf

That was fast!

I updated to the new version. It works as expected, the source buffer stays untouched!
The SPIF_Receive function is updated too - good job.
I'll do some more in depth testing an will report.
One more thing to consider for fututre releases:

Im tinkering with Azure RTOS. You might add a selection in the conf file togehther with CMSIS V1/V1 in order to use the RTOS sleep function.
