ESP32H2 usb boot after powron

[gaysin1111]

when power is supplied (smoothly) from a laboratory power source, for example, it goes to the USB bootloader. I will say right away, the connection diagram according to the datasheet is similar to DEV BOARD schematocs. IO8 IO9 are pulled up through 10 kOhm to Vcc, EN through 10 kOhm + 1 μF.
At the same time, if you pull the reset after powering up, the μF starts. After which the bootloader goes to UART normally, is flashed, works.

Are you sure you don't have a capacitor on IO9, e.g. to 'debounce' a button that might be on there?

here is my schematics for ESP32H2 tests.
