Description
Hello, I am getting a hardfault (INVSTATE) in nlrthumb.c if mp_parse is interrupted with pendsv. Is this behavior expected ? Could someone shed more light on the cause ?
Here's some info from GDB:
Breakpoint 1, HardFault_C_Handler (regs=0x2001fcc8) at stm32_it.c:144
144 if (!pyb_hard_fault_debug) {
