Other Parts Discussed in Thread: BQSTUDIO
Hello,
I’m using the bq27542-g1 gauge. I have created the golden image from a calibrated and working gauge. The bqstudio confirmed a successful download.
I flashed successfully (regarding to bqstudio) this golden image on another bq27542-g1 gauge. Now the gauge is not responding (no connection to the gauge). Using an oscilloscope, I figured out, that the gauge is responding to the addresses 0xAA and 0xAB with an acknowledge. But that’s all, after the acknowledge the gauge holds the I2C bus on low for around 50ms. After that time, the bqstudio reports EV2x00 adapter USB timeout.
Is there any chance to get the gauge working again?
Attached you can find the golden image file I flashed on the gauge.
Kind regards
Kevin
