Tool/software: Linux

Hi,

I have used EV2400 evaluation board for calibrating my bq27510g3 fuel gauge IC. I export the results after calibrating with battery management studio, via golden image files (0510_4_00-bq27510G3.bq.fs , 0510_4_00-bq27510G3.df.fs, 0510_4_00-bq27510G3.srec). When i try to write these files with a sample C source code (for linux) from SLUA801 to my custom board, the IC was entered in ROM mode but not exit and the I2c Address is 0x16.

how can it exit from ROM mode? I have used commands for exit ROM mode (0x0F to 0x00 register and 0x0F to 0x64 register)

Regards,

Hi,
This command is exist at the end of golden image file and also i used this command with i2ctools (#i2cset 1 0x0b 0x00 0x000f w -y) but it dos not work and i2c address is yet 0x0b.
Thanks for replay.

You need to send it to addr 0x16, that's the address for ROM mode.

With i2cset, we should use 7-bit addressing (0x16 >>1 = 0x0b). The i2cdetect command shows that there is a 0x0b device on the i2c bus. I test it also with gauge lib from ti (address 0x16 using 8-bit addressing), but not work.

Is there any way to recover the IC to its default state? is there ay help?

You can try to use Windows and an ev2300/ev2400 along with bqstudio to recover it.

I have used ev2400 along with bqstudio to recover, but the IC was not recognized (may be because of changing i2c address )

Do you mean you changed the address of the gauge? In ROM mode bqstudio doesn't recognize the gauge automatically. However if you were to open it and then manually select the bq27510 gauge and then open the fw tab and click execute, you should be able to recover the gauge.

I have done the above operation, but bqstudio doesn't recognize it.
