JTAG on imXRT1051xxxxB

Hello,

I am trying to program my 1051 on a custom PCB via JTAG (LPC Link 2) but keep getting an error "localhost:2331: No connection could be made because the target machine actively refused it." I have another board that uses a 1062 and have no issues programming that.

I am able to program the flash on the board with the 1051 and it boots just fine. Looking at the schematics everything seems to be correct so I'm not sure what the issue is. 

The only thing I can think of is the eFuse settings that I am able to change using the NXP MCU Boot Utility. On the 1062 I have the Direct_BT fuse set to disabled (it always has been by default) but on the 1051 that fuse is set to enabled by default.

However, looking at the fuse map for both the 1050 and 1060 series, that bit in the fuses is labelled as reserved.

Is it possible that setting the Direct_BT fuse will solve this issue? I've not been able to find anything out about this fuse elsewhere online.

Thanks,

Nick

It made no difference, the issue lies somewhere else.
