Tool/software: Linux
I am initializing the pointer at A8 side and sending its address to dsp using Syslink , I fill the data with some values . I read those values on DSP side and Update these values and able to see the correct updated value from A8 side . But after i mmap the device fb0/1/2 at same pointer location, The data updated by A8 is displayed on screen but DSP values are not updated to the new values . Similarly if i update that buffer from DSP side the values at A8 side are unchanged and nothing is updated on Screen as well.
Can some one help me with this problem ?
