A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hello . The memory region for rxbuffers 0x30000100 is not configured in MPU

Also the tx descriptors 0x30000060 region is not configured in MPU

Put Tx descriptors to 0x30000000 and configure the MPU for that region
