When I use the link_control() function to send 64 bits of data from IPU to DSP, why is 32 bits lost?
If the data transmitted between IPU and DSP can only be controlled within 32 bits, why can a total size of 64 bits array be accurately transmitted to DSP?
In addition, in the daily debugging, the problem of log loss often occurs, I would like to ask why this is, is there any way to improve?
Below is the validation code and the corresponding log:
