Part Number: BQ27426EVM-738
The customer uses BQ27421EVM-G1A to acquire data.In another configuration,- BQ21040EVM-777- EV2300- Electronic load- Battery used by customersAlso, they use bqStudio.There was a message that an error might occur in log data while data acquisition is being performed.I did not own BQ27421EVM so I ran it on BQ27426EVM-738 instead.As a result, the following error occasionally occurred during incoming data.

This occurs both during charging and discharging.When it occurs, it seems that we can not temporarily access the EVM from the PC.I would like to know the cause and measures to be taken.
Thanks, Masami M.

In reply to Masami Michino:
I do not have EV2400 and TI gauge GDK.FW Ver of EV2300 is 3.1c.
A battery is connected to the gauge, and voltage is always applied.A voltage is supplied from the regulated power supply to the I2C pull-up resistor.
Please try this with an EV2400. Something causes the I2C transactions to fail with the EV2300. I can't debut this remotely without access to your setup.
