Hi,
We have design to use bq27510-g1 as gas gause for a omap3 system and we can read current, temperature and flash data via i2c bus, but we use i2c to set and read back the value of BAT_GD PRI and FN. The BAT_GD pin allways measured high since we have 10k resistor pull it high as it's OD output to control our bq24123. We can read the flash data as we setted anytime even if power down and power again with battery re-plug, It looks like bq27510 always works as default but not flash setting effective.
We only target to make the battery side TS pin connect to bq27510, and if the temperature in the safe rage BAT_GD of bq27510 output low and only if temperature out of range, BAT_GD output high to disable our charger.
The questions are:
1. How to step by step since we have new silicon here?
The question contains how about "firmware" "golden image" "in circuit debug" "learning" "calibration"
2. Is there any problem without such "golden image" putted in?
3. How to make the silicon working in circuit? we currently have not got EVM board from distributor.
4. What's is the right sort of byte read and write for flash?
With Best Regards.
