trigger interrupt by memory write

[sabine_s]

I would like to trigger an interrupt by performing a memory write to a hardware register, for example, by writing to a GPIO register.

Which i.MX8QM peripheral block would be best to use and how would I configure it for this purpose?

Thank you for your advice!

Hi Sabine

one can look at linux MLK-19305 gpio commits

https://source.codeaurora.org/external/imx/linux-imx/log/?h=imx_4.14.98_2.0.0_ga&qt=grep&q=MLK-19305

Also additional example was sent via mail.

Best regards
