Part Number: BQ28Z610
Other Parts Discussed in Thread: BQSTUDIO, EV2400

Hi Team,

I am programming gauge firmware file with the help of Bqstudio out of 20 boards I could able to program 11 boards successfully

In case of 2-3 boards, execute automatically was checked, but it can't able to execute, now those boards are not getting connected with Bqstudio

In 2 boards even execute automatically button was not checked, programming didn't execute successfully may be due to some connection issue now

these boards also not getting connected to gauge, how I can recover these devices

Have you tried reprogramming the srec file? Sometimes that will work if the gauge is still in ROM mode. You can also try removing and restoring the cells to force a power-up reset. This may help to recover as well. Otherwise, you may have to replace the device. I have also run into cases where bqStudio hangs when programming the device and it has to be restarted. You may also want to uncheck the Execute Automatically box and press the Execute button manually after the srec has completed loading on new devices.

Hi Tec
> You can also try removing and restoring the cells to force a power-up reset
Did but no luck .
What do you mean by replace by device ? If device becomes faulty ? why this is happening because in one some case it simply programming gets failed and device become unacessible.

I do not have answer as to why some of the boards failed to program. There could have been a noise problem during programming or perhaps there was a power supply issue as discussed in the e2e link below. If you cannot regain communications with the device, then the device will need to be replaced with a new one.

if the gauge is in ROM mode, the device will not be automatically detected. Can you verify what firwmare version you have on your device. Also pls verfiy the hardware version of your device by following the instructions below and let me know what results you get.

What result did you get when you followed the instructions in the word document? 0x9100 or 0x9101?
Try reprogramming the boards with the default firwmare and then exiting ROM mode. Maybe your golden file somehow gets the gauge corrupted.
thanks

i have attached it. Also, can you confirm if you are using ev2300 or ev2400 ? What firmware version is on which ever you are using. If it is the ev2300 make sure you are using v3.1m or 3.1r. If ev2400 make sure it is v0.18

thanks

Hi Onyx ,

I am using EV2300 i have updated firmware version to 3.1 m. I will try to update them to default firmware version . If i remember correctly
when i am trying to update firmware of above mentioned two boards , they are sending message like No acknowledge from device , how i can program those device to default firmware .

if the devices are NACKing for programming the firmware, then it means they are likely damaged and the IC needs to be replaced.

thanks
