Tool/software:
Dear expert,
Recently, I found that AM2732 can cause ethernet transmit interrupt (MSS_CPSW_FH_INT) to be abnormal in some cases.
My case is like this: disable all interrupts through Os, send Ethernet messages ten times in a loop, and then restore all interrupts through Os.
By analyzing the logic of the mcal source code, I think the first interrupt should send the first frame Frame, then in the first transmit intrrrupt continue to call CPDMA to send the remaining ethernet packets,
and trigger the ethernet transmit interrupt again.
However, the actual phenomenon is that the transmit interrupt only entered once and did not enter the second time. According to the CPDMA register, the interrupt is in a pending state and has not been restored.
May I ask if this is a known issue? If not, can you provide me with some help based on this issue?
Regards,
Ning Wang
