I know this question has been asked multiple times but solutions giving there hasn't been working,
I've got an esp32 soldered to my own designed PCB board with a UART to USB converter all that is working fine, I can get connected to my esp from the Serial monitor.
But it prints every about 0.5s:
rst:0x10 (RTCWDT_RTC_RESET) boot:0x13 (SPI_FAST_FLASH_BOOT) flash read err, 1000 ets_main.c 371 ets Jun 8 2016 00:22:57
Solutions have been to make sure to have 3.3v on the esp. I find it unlikely to have anything to do with it, 'cause its voltage range goes from 2.6v to 3.6v, but anyway I have tested it with an advanced transformer and a multimeter to check that there was 3.3v on the Vcc pin (didn't change anything).
All help would be appreciated.
Here is a bit more info:
I've also connected a 10uF capacitor (someone told me to try that).
If I pull IO0 to ground, it prints waiting for download in the serial monitor and I can almost upload the program, this is what I get:
THERE IS NO CONNECTION BETWEEN NEIGHBORING PINS
(I have checked with multimeter)
