Hi Team,

I'm using USB-PD-CHG-EVM-01 board and also found single cell issue in v7.0.2 as this link showed:

https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1094787/tida-050047-battery-charger-configured-by-tps25750-to-single-cell/4094986?tisearch=e2e-sitesearch&keymatch=TIDA-050047%25252525252520%252525252525201s#4094986

But I found a new issue after use PatrickAussems.bin which Chuck provide in above link, the connection between BQ25792 - EV2400 - BQ studio always showed Device ACK error.

With v7.0.2, it works well and I can read/write BQ25792 in BQ studio.

Could you help check it?

Thank you!

Hi Team,

When I use v7.0.3 to create a 2s configure, /cfs-file/__key/communityserver-discussions-components-files/234/2s_2D00_703.bin

But the BQ studio can communicate when BAT only, once Adapter plug in or Adapter only, it will shows ACK error.

Could you help check the issue? Thank you!

Hi,

Can you provide the I2C log and your project file (.json) so we can take a look?

Our expert on this will be back next week so I will see what help I can provide you while he is out of office.

Regards.
