Part Number: BQ78350
Other Parts Discussed in Thread: BQSTUDIO, , BQ76940EVM, EV2400,

BQstudio does not communicate with BQ78350 on the BQ76940EVM, it needs firmware update first i think, but the file to support this looks corrupt SLUC572A.zip

    Hi,

    On a new EVM, BQStudio should be able to communicate with the BQ78350, even if the firmware is not the most recent version. Did you apply voltage across the BAT+ and BAT- pin and press the Boot button? Did you connect the EV2400 SMBus output to the SMBus port on the EVM? Are the jumpers connecting GG_SCL, GG_SDA, GG_PWR, and GG_ALERT populated on the board?

    The latest firmware for this device is located here: https://www.ti.com/lit/zip/sluc594  (version 1.04)

    The BQ78350-R1A comes pre-loaded with the latest firmware and is recommended for new projects.

    Best regards,

    Matt

    Hi, thanks for the quick reply. No solution yet , however. The BQ78350 on the EVM has fw 1.04 while the BQstudio supports up to 1.03. I tried to upgrade BQstudio to latest version V101, but it crashes.

    Upgrading BQStudio to the latest version should definitely help since the newer version will include fw 1.04.

    Maybe try uninstalling BQStudio and then re-installing the new version. Make sure to copy the installer to your hard drive and click 'Run as Administrator'.
