Firmware crash #1

Closed fifteenhex closed 7 years ago

fifteenhex commented 7 years ago

I saw somewhere else that you were seeing the firmware crash after loading. This seems to be because of not properly resetting the chip before the mmc subsystem tries to init the sdio card.

The driver built from your source starts up correctly with my device tree (https://github.com/fifteenhex/linux/blob/bde4b4a1ea3a8d6b7c757143e0724be9dddd0b36/arch/arm/boot/dts/sun8i-h2-orangepi-zero.dts) and crashes a bit later on:

To be honest, I am stll working on the same problem. :-(

I'm able to have the firmware load every time now. There is a bunch of stuff coming out from the driver about commands timing out which I think is to do with the interrupt not being setup.

I have the driver working now (wireless scan works at least..) . Adding this to the make file seems to be the main thing: ccflags-y += -DCONFIG_XRADIO_NON_POWER_OF_TWO_BLOCKSIZES

It seems like if that isn't that the firmware upload is corrupted or incomplete and that's why it crashes soon after booting.
