Looks like you are on the right track. I'd suggest using a 400KHz i2C bus, as the sensor does send a lot of data.
But you stopped just short of the critical question... What is the result of your call to:
status = vl53l7cx_init(&Dev);
If you can 'see' the device at address 0x29, you should be able to call this function.
It sure looks like you are running on some variant of an STM32. That means you don't have a byteswap issue. (This is the most common I2C failure.)
I'd comment out your demand that the SensorID be 0xF0.
In our code, I see:
status = vl53l5_read_multi(&L5Dev.dev, 0x00, &device_id, 1);
status = vl53l5_read_multi(&L5Dev.dev, 0x01, &revision_id, 1);
uart_printf("Sensor Dev ID: %d, Rev: %d\n",device_id,revision_id );
in your code you appear to be reading 0x7fff and expecting the device ID.
0x7fff is an interesting register. It has two purposes; It's the last byte of the firmware download and it's the 'go' byte. Writing to this byte is going to try to start the program and you have not downloaded the code yet.
Remove that bit of code and see what happens.
(Perhaps some of my French collogues can chime in. My French is sorely lacking here.)
