Allocating ddr memory for PRU usage

Hello,

I’m using the beaglebone black using Debian Wheezy currently on the website.

I’m trying to allocate memory in ddr for PRU to write data to. Inside “/sys/class/uio/uio0/maps/map1/size” it report a hex of 0x40000 or 262144 bytes of data. I try changing the size using "modprobe uio_pruss extram_pool_sz= " but nothing happens as in no error message and looked like it works. when I checked the size again the size stayed the same.

I have no idea what is wrong.

Figured it out. Needed to unload uio_pruss using rmmod before trying to set a size
