Our customer has a issue.
It is that the order of Asynchronous Memory Write and GPIO Output is changed.
In the program code, the order as follows.
1. 1st Memory Write
2. 2nd Memory Write
3. 3rd Memory Write
4. 4th Memory Write
5. GPIO Output is High
In The timing of the output signals, during the 1st Memory Write (CS is Low), GPIO Output becomes High.
I guess that it is because the DSP core does not wait for the Memory Write to be completed.
What should I do to fix this issue?
Best regards,
Daisuke
