FAQ
* Why are there are 2 different flash chips?
- the idea is to make the device (almost!) unbrickable and very easy
to recover
- NAND will hold the main loader (U-Boot) and the Linux image and
will be the default boot device
- NOR will be write-protected by default (with WP jumper available on
the board) and will hold a recovery bootloader (and other essential
data, like Wi-Fi calibration)
- a dedicated boot select switch will allow changing between NOR and
NAND
No Idea how MTK factory calibration data is individual per-device.
If it's possible, I'd like to propose a archive of the
radio-calibration / MAC-Address partition.
So this would be used to enable people download their calibration data
for their serial-number and
make it "unbrickable" with an SPI clamp.
What do you think?
Best

Hi David
indeed, I fully agree, the calib blob holds no privacy relevant info.
once the vote concludes positive I have the mandat to talk with the ODM.
the idea is to provide a http/rest endpoint for the ODM to
a) grab a blob with the serial number and other TBD data to be place
inside the flash
b) upload the calibration data for backup storage,
John
