I.MX8M SPI device

pjw — Tue, 13 Oct 2020 05:32:58 GMT

I'm using I.MX8MQ EVK and will development custom product.

I have a plan to use a spi device. Currently, we are operating with androidoreo. Do we just need to modify the dts file? And I wonder how to modify it.

One more rudimentary question is, if the above processes are successful and the spi device is connected after the boot (assuming you've even raised the device driver), how can I confirm the connection?

If you can give me any information, please reply.

Hi pjw

for using spi device one can add driver for it using linux guidelines and rules

as android is based on linux. In particular one can look at sect.3.8 SPI NOR Flash

Memory Technology Device (MTD), sect.3.8.5 Menu Configuration Options

i.MX Linux Reference Manual

for testing use unit test:
