Hello
We would like to inquire whether the STM32N6570-DK board and the NUCLEO-N657X0-Q board support Ethernet TSN (Time-Sensitive Networking). Additionally, we would like to know if there are any STM-provided drivers or libraries for Ethernet TSN for these boards. If such resources are available, we would appreciate it if you could share them with us.
Currently, we are working on Ethernet transmit and receive functionality on the NUCLEO-N657X0-Q board using the driver generated from STM32CubeMX. However, we are encountering a HardFault when attempting to transmit in interrupt mode. The code execution jumps to the HardFault handler at the following segment in ETH_Prepare_Tx_Descriptors:
if (txbuffer->next != NULL)
{
txbuffer = txbuffer->next;
/* Set buffer 2 address */
WRITE_REG(dmatxdesc->DESC1, (uint32_t)txbuffer->buffer);
/* Set buffer 2 Length */
MODIFY_REG(dmatxdesc->DESC2, ETH_DMATXNDESCRF_B2L, (txbuffer->len << 16));
}.
We have attached our code files for your reference and would greatly appreciate any guidance or suggestions to resolve this issue.
Thanks & regards
Akshitha Pattem
