Get a problem with ETH on H7 family.
On my dev-board-stand-with-ugly-wired-beard (pic.1) Nucleo_h743zi2+ Dp83869EVM my project works fine.
Project (.ioc in attach) generated by CubeIDE, with some adds:
1) MPU:
/* Disables the MPU */
HAL_MPU_Disable();
/** Initializes and configures the Region and the memory to be protected
*/
MPU_InitStruct.Enable = MPU_REGION_ENABLE;
MPU_InitStruct.Number = MPU_REGION_NUMBER0;
MPU_InitStruct.BaseAddress = 0x30040000;
MPU_InitStruct.Size = MPU_REGION_SIZE_16KB;
MPU_InitStruct.SubRegionDisable = 0x0;
MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL1;
MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS;
MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE;
MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE;
MPU_InitStruct.IsCacheable = MPU_ACCESS_NOT_CACHEABLE;
MPU_InitStruct.IsBufferable = MPU_ACCESS_NOT_BUFFERABLE;
HAL_MPU_ConfigRegion(&MPU_InitStruct);
/** Initializes and configures the Region and the memory to be protected
*/
MPU_InitStruct.Number = MPU_REGION_NUMBER1;
MPU_InitStruct.BaseAddress = 0x30044000;
MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0;
MPU_InitStruct.IsCacheable = MPU_ACCESS_CACHEABLE;
HAL_MPU_ConfigRegion(&MPU_InitStruct);
/** Initializes and configures the Region and the memory to be protected
*/
MPU_InitStruct.Number = MPU_REGION_NUMBER2;
MPU_InitStruct.BaseAddress = 0x30040000;
MPU_InitStruct.Size = MPU_REGION_SIZE_256B;
MPU_InitStruct.IsCacheable = MPU_ACCESS_NOT_CACHEABLE;
MPU_InitStruct.IsBufferable = MPU_ACCESS_BUFFERABLE;
HAL_MPU_ConfigRegion(&MPU_InitStruct);
/* Enables the MPU */
HAL_MPU_Enable(MPU_PRIVILEGED_DEFAULT);
2) linkscript:
/* Modification start */
.lwip_sec (NOLOAD) : {
. = ABSOLUTE(0x30040000);
*(.RxDecripSection)
. = ABSOLUTE(0x30040080);
*(.TxDecripSection)
. = ABSOLUTE(0x30040100);
*(.RxArraySection)
} >RAM_D2
/* Modification end */
3) custom changes ethernetif.c and DSP driver for dp83869. Like:
static err_t low_level_output(struct netif *netif, struct pbuf *p)
{
...
/* Clean and Invalidate data cache */
SCB_CleanInvalidateDCache();
HAL_ETH_Transmit(&heth, &TxConfig, ETH_DMA_TRANSMIT_TIMEOUT);
return errval;
}
This config works fine for me.
But when I use custom board with STM32H743II with this project, I cant ping my board.
Pinout almost the same.
For now i find out - MCU don't generate any signals on Tx0-Tx3 pins, but Rx0-Rx3 pins work well.
Any ideas?
