Hi all,
I am building a custom board using a NXP RT1064 crossover processor and I want to implement FreeRTOS+TCP as communication stack.
Therefore I had a look on the actual +TCP download package which has version 4.0.999 and I was happy to find a network interface driver for RT1060 (NXP1060) which is appart from not having an internal FLASH the same chip as RT1064.
I implemented the +TCP sources into my MCUXPRESSO project and found out, that the latest compatible MCUXPressor-SDK is version 2.12.1 (from fall 2022).
I was able to compile using SDK 2.12.1 without any errors nor warnings and when I run the code I get the following debug outputs:
[FreeRTOS_AddEndPoint] FreeRTOS_AddEndPoint: MAC: 30-4c IPv4: c0a80001ip
[prvIPTask] prvIPTask started
[xSetupPHY] Starting PHY initialization.
[prvNXP1060_NetworkInterfaceInitialise] Configuration successful. Waiting for link to go up and auto-negotiation to complete.
[xWaitPHY] Link up.
[xWaitPHY] Waiting for auto-negotiation to complete.
[xWaitPHY] Auto-negotiation complete.
[xEMACInit] ENET initialized.
[prvNXP1060_NetworkInterfaceInitialise] Driver ready for use.
So far, I was quite happy as it looks like the stack is running and the interface is up.
But I cant receive nor send anything - when the stack just runs for a while, I get the following outputs from time to time:
[prvNXP1060_NetworkInterfaceOutput] Failed to send the frame - driver busy!
[prvNXP1060_NetworkInterfaceOutput] Failed to send the frame - driver busy!
[prvNXP1060_NetworkInterfaceOutput] Failed to send the frame - driver busy!
[prvNXP1060_NetworkInterfaceOutput] Failed to send the frame - driver busy!
I put Breakpoints into the IRQ handler in “fsl_enet.c”:
- ENET_TransmitIRQHandler
- ENET_ReceiveIRQHandler
- ENET_ErrorIRQHandler
but they are never reached.
The only thing, what is realized is “link up”/“link down” when I remove the ethernet cable.
So I think I missed something in the initialization maybe and I have the following questions:
- Is MCUXPresso SDK 2.12.1 the right version?
- Is there an example project using MCUXPresso SDK (maybe also ready for MCUXpresso itself)?
- Can someone point me some spots where I should have a look in the code to get more usable information or which I have to fix?
Best regards,
Marco.
