InstrFetchProhibited with SPI SDcard driver in use #1

Open ghost opened 2 years ago

ghost commented 2 years ago

Hi,

I'm testing this with a LoRa32 TTGO board, using DIO0 as the RX callback. The firmware also uses the SPI sdcard driver.

It seems like a conflict with the ISR handler.

Confirming this, I can't get the IRQ based rx handling to work. I managed to get the SPI sdcard code to work by placing the sx127x into the VSPI bus, and the sdcard in HSPI. I initialize the latter first, then I initialize sx127x. But the ISR code is not cooperating.
