No wake up possibility after a discontinuity power supplies

Hi,

Someone could help me, please?

When I remove battery on my system (NO VDD and NO Vbat on the MCU), and I connect it back, the system do not start!!!!

The only way to start the system is a NRST signal.

OR

Switch OFF and ON only the VDD power supply (VBAT still 1.8V).

What should be investigated ?

Thank's for any reply.

Stef

So the hardware works and the problem is purely software related... An the last lines in a console shows very clearly what has happened!

OS_ERR_CPU_STATE_ISR_ILLEGAL     (166 = 0xA6) *** OS-function called from ISR with high priority

Also, as You have commented out HAL_Init(), but are using HAL, then HAL_GetTick() & Co must be properly implemented in Your code.
