firmware header (occupies first 1 KB of the firmware)
|
|
- very similar to trezor-core firmware header described in:
|
|
https://github.com/trezor/trezor-core/blob/master/docs/bootloader.md#firmware-header
|
|
- differences:
|
|
* we don't use sigmask or sig field (these are reserved and set to zero)
|
|
* we introduce new fields immediately following the hash16 field:
|
|
- sig1[64], sig2[64], sig3[64]
|
|
- sigindex1[1], sigindex2[1], sigindex3[1]
|
|
* reserved[415] area is reduced to reserved[220]
|
|
- see fw_signatures.c for more details
|
|
|
|
We pad the firmware chunks with zeroes if they are shorted.
