For the production purpose my task is to program 8 esp32 Simultaneously.
So for auto reset of esp32. I am using CP2102 USB to TTL In that instead of Transistor based ckt solution I have directly shorted my IO0 to my Gnd . To always be in BOOT mode. And my Rts pin I have shorted to EN pin of ESP32.
Initially my set up is working perfectly. But thereafter my utility which I using to install ESP32, is stuck in SYNC . On checking with DSO between ENABLE/RTS with respect to gnd the waveform. It was observed when proper downloading was takingnplace. My enable was to gnd for almost 235 micro sec. And when stuck in sync it was for 189.2 micro sec. So why it is happening like this?
