Hello
We hope you can point us in the right direction. We are using the RM48952 microprocessor where we are having some issues when using DMA combined with N2HET.
The project uses a state machine in N2HET to control the communication between the processor and an FPGA.
The N2HET is responsible for signalling the start of communications, generating the clock to synchronize and activating the DMA transfer request.
On the other hand, DMA is responsible for reading 8 bits at a specific address and setting that bits in the pinout address register when a request signal is identified.
The generated clock has a frequency of 3.5Mhz and the DMA needs to change the output value in the clock’s rising edge.
In this situation we verify that sometimes the state machine freeze and other times the DMA value is not changed in the correct time.
To debug the state machine, we are using "Start HET ide", but we are only able to test the state machine isolated, not in conjunction with DMA.
There is way to test the N2HET state machine and DMA together?
Best regards,
