Other Parts Discussed in Thread: BQSTUDIO
Hello,
I have to develop a programming driver to write customer's firmware in the internal memory of a BQ27742 (using In-System Programming).
I think that I have to use the I2C interface. Unfortunately I cannot find any detailed description of the internal memory of this device and I cannot find its programming specifications.
May you share with me these pdf?
From the Technical Reference I can see that there are 64 bytes of user programmable data flash storage; but my customer's firmware has data to be programmed in these locations:
0x4000 - 0x43FF
0x100000 - 0x10FFFF
May you clarify which are the locations that can be programmed? Are only 64 bytes available (as I read in the pdf) or 64KB+1KB (as per customer's firmware structure)?
Thank you and Best Regards,
Giovanni Salvador
