Hello!

We are working in a product that comunicate with other equipments over ethernet interface over tcp/ip protocol, all works fine but sometimes something happen and just ethernet peripheral stop, all other peripherals SPI, USART, I/Os continue operating.

We use Keil TCPNET library I think that there is a error on the driver, on debug when the ethernet stop I could found that TBUS bit of ETH_DMA_SR register was set, reading the datasheet I doesn't understand how to exit from this error.

If someone had this same problem and can help me.

Thanks.

Presumably you need to free up some buffers, and then ETH_DMASR = 4 will clear the state
