Looks like PRU attempts to access PCIE1 address space. I suspect it's a bug in your PRU firmware.
MASTER PRUSS2 PRU1 TARGET PCIE1 (Read): At Address: 0x00806664 TI has tutorials how to use JTAG to debug PRU. Another option is https://markayoder.github.io/PRUCookbook/04debug/debug.html Regards, Dimitar On Wednesday, February 10, 2021 at 2:27:01 PM UTC+2 Fisher Grubb wrote: > Hi all, > > I've done a few searches and couldn't find any threads or "conversations" > in this forum/group on the remoteproc kernel module for loading firmware > onto the PRUs. > > The remoteproc framework is supposed to be a Linux standard, there are > some generic documents for it, but I've only found a general diagram and > explanation in TIs SDK docs for their implementation. > > Simple code to flash LEDs loads and runs fine, but larger, more > complicated code that also just flashes LEDs fails to load, occasionally > parts of it run, or none of it runs and the there's a bit of a stack trace > in dmesg. > > The first line of the error in dmesg is: > 44000000.ocp:L3 Standard Error: MASTER PRUSS2 PRU1 TARGET PCIE1 (Read): At > Address: 0x00806664 : Data Access in Supervisor mode during Functional > access > > Is this resource_table related?
