Missing data after 8Mbps baudrate in SPI

madhavaishriram — Wed, 16 Feb 2022 12:42:05 GMT

Hi all,

I am using MKE157256 FRDM board.

In that i am trying to read and write data through SPI bus.

Using PMOD SF3 flash device as slave device on SPI0 peripheral.

if the baud rate is less that 8mbps then i am able to read the flash device address.

Please find below pic.

If the baudrate increases to more that 8mbps then data is not coming correctly.

Please if any one has any suggestion please let me know.

Thanks in advance.

Hi @madhavaishriram

Thank you so much for using our community. I really appreciate your patience.

Regarding your issue, are you sure that the part PMOD SF3 supports rates above 8Mbps? It comes to my mind that probably it is your maximum transmission rate in order to avoid the issue.

Please let me know if you have more questions.

Thank you.
Best Regards.
Pablo Avalos.
