SDIO interrupt not detected

PIHL — Tue, 25 May 2021 14:00:18 GMT

Hello,

I try to port WHD Library from Cypress to use CYW43012 with LPC54607.

I use an interrupt mode for communication, but LPC MCU is not running SDIO_IRQHandler function. In the init of system I have a part of code for interrupt registration:

NVIC_SetPriority(SDIO_IRQn, 5U);

NVIC_EnableIRQ(SDIO_IRQn);

I was looking for interrupt on DATA1 line, but was not able to detect it with a scope.

Is there any additional configuration needed to run SDIO_IRQHandler funtion after interrupt?

Thanks,

Piotr

Does WHD Library from Cypress is included in MCUXpresso SDK? If not, we can't test it.

I suggest you referring and comparing your code with our demo

{MCUXpresso SDK folder}\boards\lpcxpresso54608\sdmmc_examples\sdio
