TMS570LS3137: LWIP FIQ and IRQ Handler

Hasan KAYNAR

Part Number: TMS570LS3137

Tool/software:

Hi,

I am working on the LWIP implementation with the TMS570LS3137 in RMII mode. Transmit and receive work perfectly in IRQ mode. However, when I try to use it in FIQ mode, only receive works, and it freezes in the transmit handler.

How can I use this in FIQ mode?

Best regards.

Hi,

I have seen these examples before in the forum but this is not exactly my problem. I don't use FreeRTOS and DHCP, I use static IP, I change the configuration of the code running in IRQ to FIQ only.

Best Regards.
