Better documentation of bootloader firmware building process

[mcuee]

It is good to have some documentation for the users to build their own firmware.

The comments here are a good start.

• https://github.com/stefanrueger/urboot/issues/5#issuecomment-1320894654

1. Using Make and urboot-gcc

   make MCU=atmega328p F_CPU=16000000L WDTO=1S AUTOBAUD=1 LED=AtmelPB5 DUAL=0 EEPROM=1 URPROTOCOL=1 FRILLS=7 MOVETO=atmega328p_autobaud_ee_led+b5_fr_ce_ur_vbl

2. Using avr-gcc directly

./avr-toolchain/5.4.0/bin/avr-gcc -DSTART=0x7e80UL -DRJMPWP=0xcfd6 -Wl,--section-start=.text=0x7e80 -Wl,--section-start=.version=0x7ffa -D_urboot_AVAILABLE=22 -g -Wundef -Wall -Os -fno-split-wide-types -mrelax -mmcu=atmega328p -DF_CPU=16000000L -Wno-clobbered -DWDTO=1S -DAUTOBAUD=1 -DLED=AtmelPB5 -DDUAL=0 -DEEPROM=1 -DURPROTOCOL=1 -DFRILLS=7 -DVBL=1 -Wl,--relax -nostartfiles -nostdlib -o atmega328p_16mhz_auto_115200bps_ev1f7_ledPB5_wdto1s_ur.elf urboot.c

./avr-toolchain/5.4.0/bin/avr-objcopy -j .text -j .data -j .version --set-section-flags .version=alloc,load -O ihex atmega328p_16mhz_auto_115200bps_ev1f7_ledPB5_wdto1s_ur.elf atmega328p_16mhz_auto_115200bps_ev1f7_ledPB5_wdto1s_ur.hex

./avr-toolchain/5.4.0/bin/avr-objdump -h -S atmega328p_16mhz_auto_115200bps_ev1f7_ledPB5_wdto1s_ur.elf > atmega328p_16mhz_auto_115200bps_ev1f7_ledPB5_wdto1s_ur.lst

mv atmega328p_16mhz_auto_115200bps_ev1f7_ledPB5_wdto1s_ur.hex atmega328p_autobaud_ee_led+b5_fr_ce_ur_vbl.hex

A few things are nice to have as well.

1) Better documentation of urboot-gcc and hexls. For example, how to use different toolchaine with urboot-gcc, say using another installation of avr-gcc.

2) It is also good to document how to make urboot-gcc and hexls working by mentioning the perl module used.

3) How to modify the Makefile to use another gcc toolchain (still using urboot-gcc wrapper)?

4) How to modify Makefile for users who can not use urboot-gcc for some reason, just plain avr-gcc.

Can you help? Being a seasoned perl programmer, I do not know what hurdles there are for someone without perl experience or a perl installation. You managed. What did you have to do? @mcuee

4. How to modify Makefile for users who can not use urboot-gcc for some reason, just plain avr-gcc.

Absolutely not recommended. I only mentioned to you as a highly competent engineer and only for a quick fix to get you to compile one particular bootloader. In reality there are so many pitfalls when using this route, eg, how to compute START and JMPWP, both of which urboot-gcc does.

[mcuee]

I see. So the recommendation is to use urboot-gcc to work. I think I can help to mention the perl module which needs to be installed, even though I do not much about perl itself.

Windows is probably the more challenging part if I want to use MSYS2 as it lacks the necessary FILE::HomeDirmodule. I do not have issues with Linux and macOS.

[stefanrueger]

Windows

Only useful if there is the avr-gcc toolchain. urboot.c only compiles with that specific compiler. Best experience is with 4.8.1 and 5.4.0,

Yes MSYS2 has avr-gcc toolchain.

I can also try out Atmel provided avr-gcc toolchain with standalone perl installation without MSYS2 (but I tend to use MSYS2 a lot under Windows).

[mcuee]

Here is an example of using avr-gcc from MSYS2.

For hexls, Strawberry Perl works out of the box.

So it seems to me the newer toolchain is pretty much the same in terms of code generration (code size).

So it seems to me the newer toolchain is pretty much the same in terms of code generration (code size).

One file is not enough to judge. Try

(make clean; make all) >& /dev/null
hexls *.hex >/tmp/a
(make clean; make all TOOLVER=8.5.0) >& /dev/null
hexls *.hex | diff /tmp/a -
make clean >& /dev/null
rm /tmp/a

This shows you where the two toolchains differ in generated code size

[stefanrueger]

I can help to mention the perl module which needs to be installed

Please do

I need to use the following command to use Atmel avr-gcc toolchain in the Path.

(make clean; make all TOOLVER=system) >& /dev/null

Here is the comparison with Atmel provided Linux toolchain, gcc 7.3 version. https://www.microchip.com/en-us/tools-resources/develop/microchip-studio/gcc-compilers#

Easier to read version. So yes I agree that the old version creates same or smaller codes in general.

[mcuee]

I can help to mention the perl module which needs to be installed

Please do

The following perl modules are required by hexls and urboot-gcc.

File::Basename;
File::HomeDir;
Capture::Tiny
POSIX
Scalar::Util
Getopt::Long

Ubuntu 20.04 (tested to be good) -- hexls and urboot-gcc work out of the box as perl and necessary perl-modules have been installed. I do not see File::HomeDir listed but it still works. https://packages.ubuntu.com/focal/all/perl-modules-5.30/filelist

macOS (to test) : install File::HomeDir using sudo if you are using system provided perl. It should also work if you use other perl version.

Windows (to test): install Strawberry Perl and you are all set. You can also use other Perl installations.

I will carry out test under macOS and Windows later.

[mcuee]

BTW, I am not able to get File::HomeDir installed under MSYS2.

$ ./hexls

Maybe the other MSYS2 installation needs some updates. I tried another Windows machine and it works fine to install File::HomeDir. But then it does not work. Therefore I think I will have to rely on Strawberry Perl together with MSYS2 for now.

Under macOS, other than installing File::HomeDir, the other thing is that you need to assemble the working avr-gcc directory. For example, I have to merge avr-gcc and avr-binuntils to have a working 9.4.0 toolchain. Unfortunately Atmel provided avr-gcc macOS x96_64 toolchains (7.3.0 and 5.4.0) do not work because of the developer signature warnings which I am not able to fix. The other working toolchain is from Arduino.

Since I have only the 9.4.0 toolchain, minor change to the Makefile is required. Similar modification can be done for Arduino toolchain 7.3.0.

It seems to me there is nothing much to improve on the build process under Linux as it is working out of the box. As for macOS. You just need to document that perl modules File::HomeDir is required. You may also want to mention that Makefile may be necessary to change the toolchain version.

Better documentation of urboot-gcc and hexls will still be good.

For Windows, unfortunately MSYS2 perl packaging is not good. We can forget about Windows support for a while. Windows users can refer to this post to build if they really want to do that (using Strawberry Perl and then modify the few files accordingly).

[stefanrueger]

@mcuee Many thanks for exploring how to use the project under Windows and MacOS, and for sharing tips for better documentation! Well appreciated.

I have updated urboot-gcc and hexls so they no longer require File::Homedir. Great tip.

The comparison table stock urboot/9.4.0/7.3.0 is great! I suspect you mixed the columns for urboot and 9.4.0, though? I believe the stock urboot decision is always the best choice, not?

Note that the urboot project does not recommend to compile with other avr-toolchains than 4.8.1 or 5.4.0. Generally, the code has lots of assembler bits in there that rely on the compiler API for creating code. It is a bad idea to use newer compilers, as they may well change that API! So, if this projects is ported to Windows/MacOS, it would need the 4.8.1 and 5.4.0 toolchains there! This is one of the few situations where an old version is actually better.

Great, now that hexls works out of the box under MSYS2 Windows. For urboot-gcc, it still complains that Capture/Tiny.pm is missing even after I installed it using cpan. Looks like MSYS2 cpan is broken.

BEGIN failed--compilation aborted at ./urboot-gcc line 18.

Edit: Copy the file Capture/Tiny.pm to /usr/share/perl5/site_perl fixed the issue.

I do not want to change the urboot Linux toolchain so I named the Windows 5.4.0 toolchain as version 5.4.0_win32. I need to use the following minor patch and then it works under Windows using MSYS2.

The comparison table stock urboot/9.4.0/7.3.0 is great! I suspect you mixed the columns for urboot and 9.4.0, though? I believe the stock urboot decision is always the best choice, not?

Yes, you are right, urboot is always the best. Table updated

[mcuee]

Note that the urboot project does not recommend to compile with other avr-toolchains than 4.8.1 or 5.4.0. Generally, the code has lots of assembler bits in there that rely on the compiler API for creating code. It is a bad idea to use newer compilers, as they may well change that API! So, if this projects is ported to Windows/MacOS, it would need the 4.8.1 and 5.4.0 toolchains there! This is one of the few situations where an old version is actually better.

I can not find version 4.8.1 but Atmel provided 7.3.0 and 5.4.0 for Linux, Windows and macOS. Now I need to figure out how to get Atmel avr-gcc compiler to work under macOS (due to all the developer signing issues).

https://www.microchip.com/en-us/tools-resources/develop/microchip-studio/gcc-compilers Atmel version 3.7.0 --> avr-gcc 7.3.0 Atmel version 3.6.2 --> avr-gcc 5.4.0

[mcuee]

I think this issue can be closed.

I will report the macOS 5.4.0 situation later.

[mcuee]

I will report the macOS 5.4.0 situation later.

This is the current problem with the Atmel toolchain avr-gcc 5.4.0. I will see how to fix it.

Results from Atmel 5.4.0 toolchain under macOS -- it may produce some bigger size urboot hex files but the space occupied is the same in the end. I also checked and the size produced by Atmel 5.4.0 toolchain under Windows produce the same binaries.

I also attached Atmel 7.3.0 build but I understand it is not supported.

In summary, I think there is nothing to be changed on your side. In case users want to build under Windows or macOS, they can refer to my experiences here. I am happy to help as well if other users encountered problems under macOS or Windows.

[stefanrueger]

@mcuee Thank you for all your hard work exploring ways to improve the urboot building process. When I get a minute I will put the results of your exploration into a "how-to-build" page; your work will be used to good effect.
