Now I try use PRU0 bare-metal application.
My setting is output 2 files. text.bin (application codes) and data.bin (data area?).
I load text.bin to 0x4a334000 (PRU0 IRAM).
And load data.bin to 0x4a300000 (PRU0 DATARAM).
But, Data Area (0x4a300000) is not same debug load (.out file by using Emulator).
I want to know correctly flow.
I want to write PUR bin file to SPI Flash. And read and load to PRU from A8 core application.
PRU link .cmd file is
