Okay so I looked more closely at the change documented by Rudi above and the back-light works as expected. :D
I looked at that last night but it was late - that's my story ...

Seems like I make one step forward and then step back again.
After updated esp-idf to the latest code i get this message

$ make flash
make[1]: *** No rule to make target 'libcoap/src/address.o', needed by 'libcoap.a'. Stop.
make: *** [/home/Glenn/src/esp-idf/make/project.mk:378: coap-build] Error 2

my libcoap dir is empty

i see it's a submodule - not sure why it's not being pulled in

Edit: recloned with --recursive worked as well. It seemed odd as initially I saw other submodules automatically pulled down but not libcoap for some reason

:D

hi guys,
what you think?
can we save ROMS to sd card (yes )
make a menue for selecting from this ( yes )
after select, ROM cpy to nmap (yes )
is no sdcard found, load "factory" 0x10000
return romdata (yes)

perhaps we can nmap sdcard (raw) too (usually yes) 8-) vfat? :idea:

best wishes
rudi ;-)

Unfortunately, we can't mmap SD cards like we can mmap SPI flash. Flash MMU only knows how to use SPI0 peripheral to talk to SPI flash chips. But copying from SD into flash and mmap-ing the flash is certainly doable.
