Ethernet HAL stopping transmitting #19

Closed ashchepkov closed 1 year ago

ashchepkov commented 2 years ago

Hello! Function HAL_ETH_Transmit_IT() from file stm32h7xx_hal_eth.c first check availability of current transmit buffer, then prepare descriptor and increment Tail pointer without checking who own next buffer. In case of transmitting many data this behavior may cause Head == Tail and DMA will stopped. When HAL_ETH_Transmit_IT() will be called next time, current transmit buffer will be owned be DMA and function return error without transmitting.

Hi @ashchepkov,

Could you please confirm that you are using the recently reworked ETH HAL driver proposed within this pull-request stm32h7xx_hal_driver#16 ?

With regards,
