SaMoRa : Progress on bootloader


Today, we worked on the bootloader 0. We updated him in order to be able to switch in recovery mode after a cold boot.

Just to remind this bootloader is for cards of trafic light, switch and remote control. The last version switch in recovery mode only if firmware 1 and 2 crash. So if the update function have a bug, it’s impossible to update the card.

Moreover, the recovery mode is a very simple firmware which is  able to listen CAN Bus and update or remove firmware and reset the card.

EDIT : A light optimization we reset after cold boot and without recovery instruction.

See you soon,

SaMaRa team.
