Michael Cardell Widerkrantz	8dca845bc1	Harmonize firmware description ... The links to firmware.md disappeared earlier so this change incorporates some of the the text there in under the Firmware heading in software.md. Also changes the names of the commands in the state machine to the same names as in the rest of software.md. Mention the Zmmul extension and what it means and possible workarounds for people developing with clang < version 15.	2022-12-02 07:45:53 +01:00

Michael Cardell Widerkrantz	c80dc53027	fw: Introduce an explicit state machine - changes protocol! ... We introduce an explicit state machine (see README). With the new states we: - combine setting size and USS to a single command. - start the device app immediatiely when having receceived the last data chunk and returning the digest. - Loop forever and wait for the stick to be removed if we end up in unknown state.

Daniel Lublin	55c5081486	Adjust and document the firmware state-machine, including USS ... In particular, order of LOAD_USS and LOAD_APP_SIZE is not required, but the need to send both is documented. This is followed up with adjustment in the host programs' Go code, to try to reinforce this. LoadApp() will take the secretPhrase parameter (to be hashed as USS), and loadUSS() will be unexported. Correct CMD/RSP lengths in pseudo-code.	2022-10-12 15:12:07 +02:00
