UDMA: TR15 hangs if ICNT0 is less than 64 bytes

Details

The UDMA always attempts to send the burst size for a transaction. If the actual ICNT0 is less than the minimum burst size of 64 the UDMA will wait for data that is never coming and will hang. If the EOL is set in the TR then the UDMA always sends the data for the last data regardless of the size allowing for the transfer to be sent.

Workaround

This can be worked around by setting the EOL to 1 in the TR
