Image 0 did not work. We now get rid of bootloader_backup_irq_table and
do this manually: We may not write to address 0 while an image is
running. So for image 0 we write the lower 8 pages to the backup
address. For all other images (ony image 1 currently) we write to
*both*, the original address *and* the backup address. This is done
because some addresses in the lower 8 pages *are* used at the original
address and the bootloader doesn't (want to) know which addresses are
which.
There are more safeguards now: We refuse to write to the active or
boot_next image (if boot_next is not boot_default). We mark the uploaded
partition as not ok.
Needs latest bootloader with commit ID a5771ae033b57.
Also get rid of genbackupisr hack: We can achieve the same thing with
avr-objcopy which doesn't need additional software.
We use the new bootloader setting for irq-save area of 0x800.
Compatible with old bootloader. Adds an additional section with a copy
of the interrupt vector table to the end of the image. This is needed by
the new bootloader and should be ok for the old bootloader.
Note that for this to work, everybody needs python installed with
the IntelHex python package. On Linux this can be achieved with
pip install IntelHex
Introduce new testing-app example.
Add a new coap error code for blockwise transfer.
Add include-file for bootloader callbacks (jumptable).
Note that only the bootloader for osd-merkur-256 will support
OTA-update, the -128 simply has not enough flash memory, so only
in the -256 we have the bootloader functions in the jump-table
of the bootloader and in the bootloader-if.h include-file.
Rename guhRF platform to osd-merkur-256, previous osd-merkur platform is
now osd-merkur-128. Also check that everything is consistent.
Add both platforms to the regression tests.
Move redundant files in platform dev directory of both platforms to
cpu/avr/dev. Note that this probably needs some rework. Already
discovered some inconsistency in io definitions of both devices in the
avr/io.h includes. Added a workaround in the obvious cases.
The platform makefiles now set correct parameters for bootloader and for
reading mac-address from flash memory.
Factor the flash programming into cpu/avr and platform/osd-merkur* and
rework *all* osd example makefiles to use the new settings. Also update
all the flash.sh and run.sh to use the new settings.
The suli ledstrip modules (and osd example) have also been removed.
