- `printf "%d" ""` triggers an "invalid number" warning on ash, so
let's use `0` as portable default for zero
- add quotes where needed to make shellcheck happy
The spi scalar calculation tool for the kinetis family is stand-alone
and doesn't use the RIOT headers. It doesn't include the ARRAY_SIZE
macro from the RIOT headers. This commit adds a local definition of the
ARRAY_SIZE macro
Keep the compiled '.bin' file to remove the need to compile it when
flashing. This remove the need to have the toolchain when flashing so
allow compiling and flashing with `BUILD_IN_DOCKER=1` without a local
toolchain.
Even if it ends up storing a binary, the file is only 34 bytes.
Get OBJDUMP from the environment instead of hardwriting the value.
This is a prerequisite to allow using `objdump` when building from docker
when not having the `arm` toolchain installed.
- fcfield is located in memory at 0x400-0x40f. Its content is only read
upon reset, therefore if in presence of a bootloader and multiple
applications, the fcfield will only be read when the bootloader
is loaded. As long as we flash at IMAGE_OFFSET > 0x410 we do not
care about the fcfield content since it won't get overwritten.
