WROOM-32E and 32kHz RTC crystal
Posted: Thu Jan 27, 2022 2:36 am
I've been using 32.768kHz XTAL with my old WROOMs 32 and 32D with no issues.
However, when I solder the XTAL to a WROOM 32E it won't start:
I'm using the same PCB, same XTAL, same capacitors. Nothing changed except WROOM. I'm flashing examples/get-started/hello_world project. The only thing I changed in menuconfig is ESP32_RTC_CLK_SRC. Same project flashed on 32 and 32E - XTAL works on 32 but doesn't work on 32E.
Do I need to change something in menuconfig for it to work on 32E?
Thanks!

Code: Select all
clk: 32 kHz XTAL not found, switching to internal 150 kHz oscillatorDo I need to change something in menuconfig for it to work on 32E?
Thanks!
