Better documentation for compiling optiboot_flash #8

Open mcuee opened 1 year ago

mcuee commented 1 year ago

It will be good to have a bit better documentation to let the user know how to build the hex file.

Right now the build scripts work out of the box for macOS and Linux. But it does not seem to work under Windows.

mcuee commented 1 year ago

Maybe the following page can be a good start. https://github.com/Optiboot/optiboot/wiki/CompilingOptiboot

Under Windows I can use git bash and Arduino toolchain to build the hex files from Optiboot github, including the following. https://github.com/Optiboot/optiboot/blob/master/optiboot/bootloaders/optiboot/makeall.mcudude.sh

However, the same environment does not work for optiboot_flash.

I am able to use MSYS2 as well for optiboot, but it does not seem to work with optiboot_flash.

Please also refer to the following.

Under MSYS2: it does not work at all.

Same for git bash.

Single hex build is mostly okay with CMD.exe but it has the same issue as optiboot, because of baudcheck.tmp.sh.

If I delete the check to enable makeall under git bash, it failed.

 Welcome to MCUdude's optiboot_flash build script!

Do you want to delete all previous files and folders (y/n)? y

You're about to build a total of 9856 hex files. This is probably going to take a while.
Are you sure you want to do this?

Press enter to run script!

Another good reference for Windows can be from DxCore. It works for DxCore optiboot_dx and megaTinyCore optiboot_x. https://github.com/SpenceKonde/DxCore/blob/master/megaavr/bootloaders/optiboot_dx/README.md

Results: https://github.com/SpenceKonde/megaTinyCore/issues/870

I can make it work under Windows as well for optiboot_x for MegaCoreX with some tweaks.

The problem is rather steange, both uder git bash or MSYS2.

$ mingw32-make clean_lst
find . -name "*.lst" -exec rm {} \;
find: missing argument to `-exec'
mingw32-make: *** [Makefile:1430: clean_lst] Error 1

$ find . -name "*.lst" -exec rm {} \;
(this is okay).

Finally found the solution for this one. The following patch works under git bash or MSYS2. But makeall still failed.
