Hi team,
My customer has 10k R0 FW device, they want to upgrade it into R1, can they upgrade the FW through MCU in production line?

Hi Team,
May I have your feedback today? Can FW upgrade from R0 to R1 by MCU I2C communication instead of EV2400+BQstudio
Hi,
Default R1 FW is available at the link below, it can be flashed onto R0 devices. One thing to note is that this is default FW and all the registers that were previously configured will need to be reconfigured, I suggest pulling the customer .gg and uploading it to new FW.

Hi Evan,
Thanks for your support. Want to double check with you:
In lab(EV2400+personal computer): User can upgrade FW by BQstudio: entor ROM mode and program R1 FW.
In production line(only MCU): Can user directly program R1 .srec file?
Hi,
You do not need to enter ROM mode to change FW.
Yes, upload the r1 .srec with parameter configurations.
Regards,
Evan
