lpspi Linux driver on IMXRT

sbabu — Fri, 20 Oct 2023 05:41:40 GMT

We have ucLinux running on IMXRT1024. I am looking for a user space application to communicate to SPI. In our Linux tree we just have driver for lpspi but not for the main SPI controller.

Can we communicate to lpspi by enabling SPIDev device example as given in Linux tree and pass the buffer to read using ioctl? or is there a different way for user application to read and write to lpspi?

Any pointers will be of help to me. Thanks .

regards

Babu

Hello, my name is Pavel, and I will be supporting your case, there are no examples in our SDK about the uCLinux, but let me get more information about the module of SPI.

Best regards,
Pavel

@Pavel_Hernandez Thanks. I understand SDK does not have ucLinux examples. This query is specific to Linux. So information about SDK example on SPI will be of less use to me.
