Hi, I'm currently trying to save data into the memory from a PRU application.
Currently I can store data up to ~12.3 MB : I can change it with modprobe uio_pruss extram_pool_sz=0xBC5798 This command works but for 0xBC5799 it doesn't. I figured this idea out from this post https://groups.google.com/forum/#!searchin/beagleboard/extram_pool_sz/beagleboard/Gb6xL7V7Z00/GtEy703CursJ and also from the eRam part on this page http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_memory.html In addition, I also assumed that the difference between 0x800000 and 0xBC5799 is link to the fact that I'm using a more recent version of the Board (beagle Bone black ) or to the kernel 4.1.21-bone-rt-r20. However, this limit of 0xBC5799 is always changing (increasing or decreasing) when I reboot my board. Did someone have an idea on the exact amount of this limit ? Rq : I didn't succeed to find it in the TRM(Technical reference manual) My other question is : Is there a way that I can save the data from PRU directly into the SDRAM of 512MB or on the SD card, or is it impossible ? If so what are the corresponding addresses or methods to use them ?
