Hello,
So, here's the setup. We have custom platform that basically copies the AD-96TOF1-EBZ board but a couple of minor changes: smaller size; single laser diode; proprietary laser diode driver circuit. We have successfully loaded the latest Raspberry Pi SD card image as well as implemented the Raspberry Pi Build instructions as described on GitHub. We have, or at least I hope so, successfully compiled and installed the Tools. The goal is to write a firmware located in /aditof_sdk/misc/ad-96tof1-ebz via eeprom-tool to the memory.
Scanning the I2C bus returns the following:
pi@raspberrypi:~ $ lsmod | grep i2c

When we try to write to the memory, the following happens:
pi@raspberrypi:~/workspace/github/aditof_sdk/build/tools/eeprom-tool $ ./eeprom-tool -m -w /workspace/github/aditof_sdk/misc/ad-96tof1-ebz/ad96tof1_eeprom.bin

Any feedback would be highly appreciated.
