Hello ESP Team, We have observed that there is voltage difference after running the ESPEFUSE.py script. Please check the attached comparison sheet. Voltages are compared with respect to programmed ESP32. Changes in voltage are observed in pins : 4, 5, 10, 13, 28, 29, 30, 31, 32, 34. Please refer to ...

We double check all the fail boards for SMT defects but no SMT defects found. Thanks again to help us in recovering the fail modules. But still on daily basis we are getting same failure in modules (2~3 Nos.) out of 600 device production. Need support for finding root cause for this issue. Further s...

Hi, Thanks, we are able to flash the FW successfully after running the espefuse.py script. Please confirm after running this script is there is any change in functionality/features of the module? Please refer the the below logs of espefuse.py C:\Python27\Scripts>espefuse.py.exe --port COM101 set_fla...

You are talking about GPIO14 or Pin no. 14?
please share the windows tool and binary to resolve this issue.

The Chip is ESP32D0WDQ5 (revision 1), there is no shorting and soldering defects in fail boards. What may be the root cause behind this issue?
We are getting 2-3 failures modules due to this issue out of 600 per day.

Hi, We are facing issues of ESP32 not getting programmed. While programming through espflash.py tool we are getting error " MD5 of file does not match data in flash! . We checked further and found below observations : 1. Voltages of OK Modules and Failed Modules are compared. It is observed that Fai...
