I am getting kernel panic error while load from kernel and dtb file via tftp. I don't know how to mount the fs in the system. I am using the LS1021aTWR development board. Below the debug error. => setenv bootargs 'root=/dev/ram rw ramdisk_size=40...
As for the interrupts, each AXI DMA/VDMA will have an interrupt port (s2mm_introutandmm2s_introut). You'll need to concatenate these signals together with aConcatIP block, and pass it into theIRQ_F2Pport of the processing system IP. Bits 0 - 7 get assigned to interrupts 29 - 36 an...
