I have a problem with loading into debugger in Keil for STM32F042

(Run to main() is off)

- normal start for example from STM32F0xx_StdPeriph_Lib_V1.5.0\Projects\STM32F0xx_StdPeriph_Examples

for STM32F030

Make sure that the BOOT pin is low if you want it to start in FLASH

Thank you, clive1.

If PA8(BOOT0) is pull down - all is OK.
