Recover imxrt1176xxx from fault state

[Jeevan]

Hello team,

We were using imxrt1176 controller....when we were using it, unexpectedly it has went to fault state and controller is not responding to the PE micro debugger...

Kindly please suggest any method to get back the imxrt1176 to its original condition or state ... so that we can work with it.

Hi @Jeevan,

Please follow the steps described in the following knowledge base article and let me know if you are able to recover the debugging capabilities on your i.MX RT: RT board recovery for debugger connect issues - NXP Community.

Hi @EdwinHz ,

Thank you for your suggestions, we will try the method you mentioned using secure provisioning tool.

But we are not using imxrt1170 eval board....we are using our custom board with imxrt1176 controller and it doesnt have usb or uart feature to use secure provisioning tool.

Hence can you suggest any method which i can use with only mcuxpresso and pe micro debugger alone to recover it from unknown state...

Hi @Jeevan,

Try doing points 2 and 2.1 of the aforementioned document. These two points would be setting your board to SDP mode by changing BOOT_MODE pins to 0001, and then doing a mass erase using MCUXpresso and pe micro debugger. Once this operation is completed, return the BOOT_MODE pins to 0010 to set it to internal boot, and try programming as usual.

Let me know if this works.

BR,
Edwin.
