IMXRT1064 FLEXSPI Hyper Flash Pooling Transfer

Lukas_Frank — Thu, 16 Mar 2023 11:49:13 GMT

Hi Dear Authorized,

I am trying to use an external nor flash on my card. I am successfully able to writing into it. But I am getting error for “kStatus_FLEXSPI_SequenceExecutionTimeout” in FLEXSPI_CheckAndClearError method during FLEXSPI_ReadBlocking operation.

Could you please help me about it?

Thanks and Regards.

Hello @Lukas_Frank,

Just to confirm, are you using a custom board or is it an EVK from NXP? If is an EVK, which one do you have (EVK or EVKB)?

Also, which NOR Flash are you using?

Best regards, Raul.

Hi Dear @RaRo ,

I am using my custom board. It includes S26KS512SDPBHV020. I just want to use my DRAM and NOR Flash memories in board. But I have implementation problems with both them.

Best wishes.

Hello @Lukas_Frank,

Just for double check, are you testing the SDK example: flexspi_hyper_flash_polling_transfer? If so, did you modify something in the code? What have you modified?

Also, if you are using the example could you please send us a picture of what is displayed at the terminal?

Have you tried this issue on one of our boards (EVK or EVKB)? Is the issue there too?

If you are not using the SDK example nor have one of our boards (EVK or EVKB) for test, can you share a demo that we can use to replicate the issue?

Best regards, Raul.
