Hello!
I'm fighting with LPC11E35
I've nerver such a problem with other LPCs, but I've never used them at 1.8v

I'v got hard fault just after starting the debug (via LPCLink LPC1768)
My target board runs at 1.8V so I'm using ST2378E (8-bit dual supply 1.71 to 5.5 V bidirectional level translator with 13Mbps guaranteed data rate)
Is it enough for SWD ?

 

Once or twice I've reached ResetISR where I'v put a brakpoint in first line(in dummy loop),
then I was able to go step by step.
But all other attempts just HardFault :>


I wonder what can be wrong
Any suggestions ?
