Tool/software:
Hi,
Do you have an example code of communication using Ethernet driver with UDMA driver on RTOS ?
Could you share it with my customer if you have ?
They cannot find an example code mentioned above in Processor SDK RTOS for AM62x. Therefore, the customer is trying to port from AM64x as a reference.
In terms of hardware, there is no difference on Ethernet and UDMA between AM62x and AM64x, so they changed addresses and parameters.
However, it doesn’t work correctly, UDMA interrupt cannot be latched.
For now, data can be queued from the upper layer application at the transmission, but when checking the UDMA statistics register, they found that the transmission completion flag was not set.
Therefore, they are checking for errors in the configuration values and parameters.
The cause is still unknown and there is no prospect of a solution.
Please share the example code on AM62x or please give them any advice how to communicate by using Ethernet driver with UDMA driver.
Thanks and regards,
Hideaki
