Hi!
I have been working with this discovery board for several weeks now and almost close to finalizing my design for a first prototype. But I always need to manually reset the MCU for my code to run from flash, I give 5V directly to Pin 2 of JP1. I ignored this problem all this while thinking it may be OK after I remove the SB1 and SB2. But then today I see that even with those removed, the MCU does not boot and I need to reset manually by shorting pins 3 and 4 of CN7. Also, as per STM8 manual only a 0.1uF is required externally as this MCU has internal POR and pull-up. But the discovery board has a 10nF only, I tried changing this to 0.1uF, still no use. Anyone faced such issue, please help. I fear the internal POR is not working well.
Thanks & Regards
