Hi
We have bought the max32664 version A IC (MAX32664GTGA+T) from Digi key for our project also we placed the order for corresponding module from SparkFun we developed the logic inside the our code and tested it with the help of module and we got the expected results while using the SEN-15219 SparkFun Sensor Hub Module, now when our PCB got ready we placed the sensor hub IC that we bought and tested same code and did not got any success,
After going through stack discussion we found that we need to update firmware to the latest firmware, as IC comes with firmware version 1.9.1 and latest updated firmware is 10.3.0 which is available on max32664 product page, So accordingly we written a script to update the firmware , also we tested this script on Sparkfun sensorhub module and it works perfectly but when we tried this on IC that we bought it is not working its firmware is not getting updated.
The reason that we suspect that in the sparkfun module the Page size is 8192 bytes where as in IC that we have bought has page size of 256 byte
Also we looked in user guide given by maxim but there is no mention how to procced further if page size is 256 in case of sensor hub IC
Also we checked the bootloader version and in case of sensor hub it is 3.0.0 which is allowing to update firmware to latest .msbl file where in IC that we have bought have bootloader version of 1.0.0
