Sysless last state on uLAN site and former RTIME FEL server
by Pavel Pisa 06 Sep '21

I have stubmed over message which seems to be from March 2021, written by Jiri Kubias > Rechecked and fixed supprot for LPC21xx & lpceurobot board. Also is fixed > eb_blink for arm-elf-gcc4.4.4 (the compiler optimise wait cycle, now it > coworks with timer1). If the message is really only 5 months old I would like to warn that I have not checked, contributed to the state of Sysless repository on RTIME server after abrupt commit of doctor Michal Sojka from 2012-12-30 which destroyed my attempt to provide PiKRON company originated knowledge to the public through sharing with and cooperation with Industrial Informatics group. I hoped in cooperation, sysless has been used by Eurobot team and I hoped that we can maintan common version, more people and studnets contributed but version on RTIME did not care about keeping history clean for merging and union with my use at company. In 2012, I have gone through all contributions made at FEE, prepared clean series/branch to integrate changes with full original commits authorship into original project - uLAN - sysless repository and done as much testing as possible, at least week of the work. I have send pull request to doctor Michal Sojka and urged multiple times that there are people from other companies who would benefit from version based on my, Petr Somlik and Roman Bartosinski effort put into uLAN project in between. But instead abrupt merge request has been committed Merge with git://ulan.git.sourceforge.net/gitroot/ulan/sysless Michal Sojka<sojkam1(a)fel.cvut.cz> 12/30/12 12:12 AM With duplicated history based in both branches on our older, pre GIT CSV work, the project would be useless for us. I have resign on cooperation in this area with IIG (unfortunately in this area only at that time). The uLAN project continues forward, I have contributed even NuttX port, Petr Smolink 64-bit Windows support etc... Mainline sysless is in use at our copany http://pikron.com/ , it continues to be used by Petr Smolink in Agrosoft products and is base of many http://alvat.cz/ projects. Roman Bartosinski contributed base of their nRF51 and nRF52 work. Some stm32f1x and at91sam7 has been contributed. Alvat used project with EfficiencyMicro chips as well but it has never been integrated. The vendor neutral basic abstraction to build bootloaders for many microcontrollers would be still interesting but attempt to union forces has been destroyed and left forces are used only to maintain the wokring base for projects which already use our sysless. Actual maintained sysless version can be found on uLAN http://ulan.sourceforge.net/ project site in GIT https://sourceforge.net/p/ulan/sysless/ci/master/tree/ and mirror on PiKRON company GitLab https://gitlab.com/pikron Clean patches prepared against this repository are welcomed, but expect regular review process to ensure sustainability of the project. I have tested alterantives for newer small MCUs based projects at PiKRON.com and Elektroline.cz based on project with real community with cooperative people. I have long term knowledge of RTEMS (first tested about 1994) with more my contributions and write access after approval of patches on mailing lists. But that system is targetting a little larger systems and I did not make it fit with TCP support into 500kB of LX_RoCoN. Problem is relatively limited list of supported MCUs focusing mainly to space grade ones. In 2015, I have started to contribute to NuttX https://github.com/apache/incubator-nuttx it provides vendor independent and consistent header files for most MCUs families used today. I do not suggest it to multi-core/SMP hardware, there is long way to go yet. But for the most of the projects it seems promissing and more people under my advises contributed to it in last years and use it in their projects. We have even open-source Rapid Control Applications Development tools in porting to this systems https://cwiki.apache.org/confluence/display/NUTTX/%5B2021%5D+NuttX+Support+… It is used by Xiomai, FitBit, Sony, abruptly branched by Samsing and NXP. If you want to discuss with me viable infrastructure for your future projects or want to learn from our projects, then you can meet me at MakerFaire https://prague.makerfaire.com/maker/entry/1205/ I plan to share there even my knowledge about options for studnets to participate in Google Summer of Code and other projects with talk on Sunday https://gitlab.fel.cvut.cz/otrees/org/-/wikis/home https://gitlab.fel.cvut.cz/otrees/org/-/wikis/gsoc As for reamins of 25 years of my effort invested to share my knowledge with Industrial Informatics group and make it valuebale player in open-source community, that effort has been lost and intentional lie to block my further participation and to gain full control over people I have introduced to the group has been acknowledged by doctor Michal Sojka in 2017 year, so my input to the remains of my work there is minimal.

Rechecked and fixed supprot for LPC21xx & lpceurobot board. Also is fixed eb_blink for arm-elf-gcc4.4.4 (the compiler optimise wait cycle, now it coworks with timer1). ---

Změna URL repozitářů projektu uLAN (sysless, uLUt, uLAN, ...)
by Pavel Pisa 30 Jun '13

30 Jun '13

Upozornění pro všechny, kdo používají knihovny sysless a nebo některé další související knihovny ve verzi spravované na serveru SF.net v rámci projektu uLAN http://ulan.sourceforge.net/ SourceForge přešel na novou platformu Allura a s přechodem došlo ke změně adres všech stavajících repozitářů. Obecně cesty ze tvaru git://ulan.git.sourceforge.net/gitroot/ulan/ulan-top ssh://loginname@ulan.git.sourceforge.net/gitroot/ulan/ulan-top přešly na tvar git://git.code.sf.net/p/ulan/ulan-top" ssh://loginname@git.code.sf.net/p/ulan/ulan-top" Repozitáře na původních adresách i nadále existují, ale nejsou aktuální a není do nich možný zápis. Je tedy potřeba přejít na adresy nové. Update skriptů a odkazů v rámci projektu uLAN byl provedený. Případná opomenutí hlaste. Pokud máte kopií repozitářů více nebo používáte více odkazů na vzdálené servery, tak se vám může hodit skript, který v rámci jednoho repozitáře provede update odkazů v řídicích strukturách ".git". Skript je ke stažení z aktualizované větve projektu ulan-top http://sourceforge.net/p/ulan/ulan-top/ci/master/tree/scripts/sf-update-git… Skript je možné volat i procelou hierarchii submodulů voláním scripts/git-sm -e $(pwd)/scripts/sf-update-git-url například z projektu ulan-top. Dále je potřeba pohlídat, který projekt používáte jako top level. V původním nasazení byla cesta "ulan" pouze odkazem na repozitář "ulan-top". Při konverzi ovšem došlo k vytvoření dvou kopií top level projektu. Budu se to snažit nějakým způsobem vyřešit, ale do doby, než jednu cestu zruším nebo mi pomohou na SF.net obnovit linkování (sám nad ním nyní kontrolu nemám) tak upozorňuji, že mnou spravovaným repozitářem pro nejvyšší úroveň projektu je repozitář "ulan-top".
