I can not update my Primer now, before ,it is OK.
But , after I download a stm32 program( I get and modify it from other platform board), the primer can not work , when download again(I download the circle OS ,the right program),
it said:
"!!! Error 100: Unexpected state after powering up the debug module."
" Unable to read IDcode."
"Please check that the target is connected."
My be I update the wrong program make it work like this.
the wrong program in RCC set like this:
/* PLLCLK = 8MHz * 9 = 72 MHz */
RCC_PLLConfig(RCC_PLLSource_HSE_Div1, RCC_PLLMul_9);
but ,the Primer 's crystal is 12MHZ, not 8MHZ, and I update with 8MHZ.
Is it the problem?
How can I update my Primer normally again?
Thank you.
