Hi, I am running 4.1.21-bone-rt-r20, Debian GNU/Linux 8.6 (jessie). I run a PRU program with default DRAM size of 256KB , this works fines but when I tried to increase the external memory to 8MB I got a buss error

Anybody know how can I get rid of this bus error? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
