1.EEPROM writing issue.

we follow below step to write EEPROM 1a>>2>>3，Read All EEPROM >>GUI map，DATA indicate 0

but EVB doesn't have output and crystal doesn't oscillate. VDD = 3.28V, VDDO = 1.81V, PDN = 2.57V

below is setting file

OLS_20250721.tcs

I2C address also weird.GPIO 1 H=0x7F, MID = 0x7D, L = 0x7C soft ware version is v1.7.9.1

    Brian,

    Do you have time this week for a live debug? This may be the fastest way to determine the solution. This will likely require reprogramming the EEPROM.

    Is the setting file before or after writing the device? I notice that the I2C address is listed as 0x7F in the header of the file.

    Thanks,

    Kadeem
