Need help with esp32 eFuse values
Posted: Tue Jun 29, 2021 7:08 am
Here are some eFuse values I got from espfuse.py summary :-
1. Can anybody explain to me that what does CLK8M_FREQ = 51 means ? I mean what speed does 51 specify ? is it running at 40mhz or 80mhz ?
2. I wish to set flash voltage to 1.8v forcefully, what should be XPD_SDIO_FORCE and XPD_SDIO_REG values ? I think it should be true for both, but i dont want to currupt my only board, so i am asking for confirmation.
3. How do you write boolean values with espfuse.py ?
Code: Select all
XPD_SDIO_FORCE (BLOCK0): Ignore MTDI pin (GPIO12) for VDD_SDIO on reset = False R/W (0b0)
XPD_SDIO_REG (BLOCK0): If XPD_SDIO_FORCE, enable VDD_SDIO reg on reset = False R/W (0b0)
XPD_SDIO_TIEH (BLOCK0): If XPD_SDIO_FORCE & XPD_SDIO_REG = 1.8V R/W (0b0)
CLK8M_FREQ (BLOCK0): 8MHz clock freq override = 51 R/W (0x33)
