You can connect reset of fx3 to eeprom reset as well so that eeprom also gets reset when fx3 is reset.
I use the 24M02, same exact chip and connections as the FX3 kit.
This eeprom has no reset pin !!!
I am using a jumper to manually reset.
is this problem related with bad de-bouncing of reset line ?
is the FX3 chip sensitive to that and confuses the eeprom ?

When FX3 is reset, if SDA was low, then then there is a problem. When FX3 tries to boot again, I2c master sees the I2c bus to be busy and hence EEPROM reset would be necessary. This is an expected behavior.
Yes I know this is the expected behavior.
What I learned with this is that the reset line of the FX3 must stay clean during the boot from I2C.
An hand made reset with a metallic tip or a jumper has a number of contact bounces that may trigger
another reset while the load is already ongoing and there is a probability to stop the process when the SDA is low
Then it will stay low as FX3 will not clock it out of that state on the next reset (as it assumes the bus is busy).
Nice dead lock
Well if anyone needs to provide the reset line to the user/outside-world it better to debounce it clean.
Tks for help.
