Hello,
I am writing a driver for ethernet Cortex M7 running on FreeRTOS.
I am trying to send data through ENET1 RGMII block to the external phy chip.
The TDAR bit in the TDAR register does not get cleared when no additional ready descriptors remain in the transmit ring.
In the reference manual, chapter 11.6.4.1.5 Transmit Descriptor Active Register - Ring 0 (TDAR)

Can anyone help me understand the missing link.
Hardware used: Variscite IMX8MP carrier board with Co-processors Cortex A-53 and M-7
Thanks!
