The memory mapping error on Rpi5 was caused by unusual memory PAGE_SIZE, usually on linux it’s 4KB, but on RPi5 it’s 16KB, the driver didn’t account for that. The XTRX gateware was updated to support 64 bit DMA addressing and is now working on Rpi.
I just need to double check the gateware update procedure, as now gateware consists of two images. I’ll post the instructions tomorrow.
