Error when doing a dma transfer with XDMA driver after a partial reconfiguration with XVSEC mcap driver #243

Closed inigodiezulzu closed 4 months ago

inigodiezulzu commented 7 months ago

First of all with both drivers installed I use the XDMA driver for dma transfers and it works fine. Then I partially reconfigure the fpga successfully and when I do a dma transfer again I get an error. In order to be able to use the XDMA driver again I have to reinstall the kernel module.

Error:

dev/xdma0_h2c_0, write 0x8000 @ 0x80010000 failed -1.
write file: Unknown error 512

Does anyone know the cause of this problem and give some suggestions?
