I hope I find some day some time to test RTEMS on TMDX570LC43HFK which I have long time there... I hope that it would work with OpenOCD, it should be functional without Flashing. I am happy that this work continues and I have call with Premek today to check that he has received your other e-mail. He is happy too that his thesis work has some use and promised to reply to your by another e-mail in two, three days to have his personal reply recorded. Generally we agree with change of our RTEMS contribution to BSD-2-Clause. Keeping reference to the university and authors listed is preferred. By the way, as I have announced earlies, Michal Lenc's thesis on RTEMS CAN/CAN FD support progresses https://gitlab.fel.cvut.cz/otrees/rtems/rtems-canfd/-/tree/master/lib/candrv This week, he has implemented rough initial version of connection of rtems_filesystem_file_handlers_r (can-bus.c) to FIFOs system ported from LinCAN. Not tested yet... This work has plan to target Zynq system but if there is some project in which we can participate by targetting our CAN work more to TMS570LC4357, we would consider to rearrange priorities. I have bought two BeagleV-Fire boards to my company as well https://www.beagleboard.org/boards/beaglev-fire and it could be nice target where we can test RTEMS for hard realtime in addition to Linux and NuttX. Again if there is for example some ESA or other project which could use our work, we can change mode from tinkering and long term investment into targeting concrete goals and terms. We plan to test our PXMC motion control HDL and SW on this platform to have prepared continuation to our previous LX_RoCoN Cortex-M based systems already used at ESA. There is some possibility that I will teach computer architectures in the space oriented course so replacement of Raspberry Pi by BeagleV-Fire and RTESM could be great demonstrator on ExoMy or other platform https://github.com/esa-prl/ExoMy Best wishes, Pavel -- Pavel Pisa phone: +420 603531357 e-mail: p...@cmp.felk.cvut.cz Department of Control Engineering FEE CVUT Karlovo namesti 13, 121 35, Prague 2 university: http://control.fel.cvut.cz/ personal: http://cmp.felk.cvut.cz/~pisa social: https://social.kernel.org/ppisa projects: https://www.openhub.net/accounts/ppisa CAN related:http://canbus.pages.fel.cvut.cz/ RISC-V education: https://comparch.edu.cvut.cz/ Open Technologies Research Education and Exchange Services https://gitlab.fel.cvut.cz/otrees/org/-/wikis/home ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

Hello Pavel, sorry for the delay, but I was busy with all sorts of things. I checked in the first round of patches. I work on cleaning up a patch set with support for the TMS570LC4357. For debugging, we use the Lauterbach PowerDebug System. Best regards, Sebastian -- embedded brains GmbH & Co.

Re: [PATCH 0/8] Add basic support for TMS570LC4357
Hello Sebastian, I am happy to see that TMS570 RTEMS support is moving forward. I hope to have some time when semester/exams ends to play with it at least a little again. I am curious which development toolas are you using. I preferred GDB and OpenOCD but there is problem that TMS570LS3137 has some problems with endianness access form OpenOCD to external SDRAM. I have some patches for that but for some branch bused on some other developers patches which has not propagated into mainline. Another missing part for OpenOCD is Flash programming support for TMS570 family. Again, I have some hacked version which was based on side branch of Andrey Smirnov. Problem is even inclusion of Cortex-R code linking TI libraries without sources as data array into OpenOCD. It would be necessary to use some loader of external code snippet into TMS570 for license reasons. Anyway, may old attempts are there https://cmp.felk.cvut.cz/~pisa/tms570/openocd-patches/ There is some set of utilities to use it from GDB in Premysl Houdek's repository https://github.com/AoLaD/rtems-tms570-utils It includes even tools to generate RTEMS style header files from TI manuals. As for the BSP documentation, you can look if something from Premysl Houdek's GSoC documents is reusable. As for TMS570LC4357 support, I would like to remind the work done by people from https://www.iri.uni-frankfurt.de https://github.com/jalmito/rtems/branches/stale Best wishes, Pavel -- Pavel Pisa phone: +420 603531357 e-mail: p...@cmp.felk.cvut.cz Department of Control Engineering FEE CVUT Karlovo namesti 13, 121 35, Prague 2 university: http://control.fel.cvut.cz/ company:https://www.pikron.com/ personal: http://cmp.felk.cvut.cz/~pisa projects: https://www.openhub.net/accounts/ppisa CAN related:http://canbus.pages.fel.cvut.cz/ RISC-V education: https://comparch.edu.cvut.cz/ Open Technologies Research Education and Exchange Services https://gitlab.fel.cvut.cz/otrees/org/-/wikis/home ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
