I'm fresh on the ESP hardware design, flowing the esp8684 hardware guide and made this board by myself. After welding, it won't work and print
ESP-ROM:esp8684-api2-20220127
Build:Jan 27 2022
rst:0x1 (POWERON),boot:0x0 (unk)
I don't know what does it mean and hard to find the same question on Google.
This is the sch and pcblayout
Waitting for your help.

You missed the strapping pin. GPIO8 needs to be pulled up, and GPIO9 needs to be high or low, depending on if you want download or SPI boot mode.

yep,That is the main point, the section is written in modle datasheet and chip datasheet, instand of hardware guide. Any way ,thank you for your help.You missed the strapping pin. GPIO8 needs to be pulled up, and GPIO9 needs to be high or low, depending on if you want download or SPI boot mode.
