Automatic in-field Due reflash

-

hi guys,

if needed reflash sam3x8e while it's sitting in physically inaccessible place, how it? in our system, have raspberry pi providing wifi connectivity internet on 1 side, connected on spi sam3x8e on other side.

we want have capability remotely reflash firmware on sam. best way done? uart work 1 sam - may have multiple sam-based heads in our system.

any ideas?

thanks,
valery

can specify needs little bit more:

  • does "physically inaccessible" mean, wiring impossible?

  • is possible, have hub-kind device, sam3x8e-devices can cabled to, has connection

  • how many devices expect?



one rough idea jtag:  
it no problem reflash due openocd. jtag allows chaining devices, should possible, connect several sam3x8e in chain, using 1 jtag-connector flash them all.

i have no idea, if openocd available openwrt. if yes, there should lot of cheap devices out there, act gateway-hub.
