Linux/AM5728: DSP memory problem

Part Number: AM5728

Tool/software: Linux

Hi,

TI, I am using the PCIE_idkAM572x_wSoCFile_C66BiosExampleProject demo， and I malloc the memory for a buffer,then I init the buffer. When I run it on the linux, I use the devmem2 + address to read the buffer,and I find the value is not same as the value that I init.

the malloc_aligned function:

Hi, Vefong,

Is the highlighted src and dst buffer from malloc_alligned done in Linux or DSP code? Are the console prints from Linux or DSP?

Hi, Vefong,

I have not heard back from you for a while. I assume the issue has been resolved. I also want to add that Linux deals with virtual address, and will be different from devmem2.
