GPIO46 eFuse

Postby nighthunter85 » Sun Aug 06, 2023 2:53 pm

Hi friends, i need to have GPIO46 pulled high during boot (its pulled by optocouplers LED) is there a way to bypass this boot check via eFuse so i could get into download mode with having GPIO46 tied to 1?

No, sorry. You can boot from flash when that pin is high, but you won't be able to properly enter download mode.
