New boards issue
by Jakub Havlíček 13 Dec '17

It seems that at least several of the new boards have the same MAC (00:0a:35:00:01:22) address which effectively blocks the network.

VxWorks on MicroZed board is ready!
by Jiri Hubacek 13 Dec '17

13 Dec '17

Dear students, we finished basic preparations for running VxWorks on MicroZed board. Please, see howto [1] for more information. The actual state is that the board boots VxWorks in KN:E-2 lab (we will test today and fix if not). Also, we tested *Task1* that was sucessfully run on the MicroZed board. The MicroZed board along with new motors can be used in the semestral work [2]. Documentation and testing is not complete, however. Therefore, we would like to introduce **MicroZed testing competition**. The purpose of the competition is to: - Hack and test the MicroZed board running VxWorks. - Find out the weak points: what does work and what does not. - Enhance the documentation. - Test as many Tasks as possible (not all the tasks can be run). - Fix the possible issues that may arise when working on semestral work. Please, send your contributions to this mailing list at: psr(a)rtime.felk.cvut.cz The most active/useful contributions will be rewarded by points. The competition ends as the teaching period [3] on Jan 14 2018 23:59. Have a nice day, Jiri Hubacek References: [1]: http://rtime.felk.cvut.cz/psr/cviceni/mzapo/ [2]: http://rtime.felk.cvut.cz/psr/cviceni/semestralka/ [3]: http://www.fel.cvut.cz/en/education/calendar.html

Dobrý den, chtěl jsem se připojit vzdáleně na desku, ale na desce stále probíhá loading: [image: image.png] Zkoušel jsem se připojit přes vxWorks dle návodu, ale vrací chybu: [image: image.png] Public key mi byl již přidán. Je nějaký krok, který je ještě potřeba udělat? Děkuji za pomoc. S pozdravem, Jan Bednář

Hello, I have a problem with homework 3 with pasting string argument from terminal to specific function. Accurately it is in main function in company file. When I call function "set_shm_company(char *company_name)" from the said main function it occurs this error: "/home/cermaj14/WindRiver/workspace/Monitor_app/company.c", line 71: internal error: assertion failed: Invalid C99 IL expression kind (./../src/eparse/lower_c99.c, line 3690) id_company = set_shm_company(d); Doesn`t matter if input parameter is argv[1] or some char d[] = "someString". I have found just one article at StackOverFlow and they mentioned it is compiler problem. Thanks for help Jan Čermák

Error while downloading files to remote system - WR
by Mykhaylo Zelenskyy 03 Nov '17

03 Nov '17

Hi, I have an issue with downloading files to remote system in WR. Both remote system and project were created as it's shown in assignment 3 and when I try to download .vxe files to vxsim, an error "Illegal flags combination" occurs. I download files as it's discribed in assignment 1 or is it some another procedure when downloading to a simulator with SHM support? Regards, Mykhaylo Zelenskyy

Problem with postel
by Jiří Kalousek 01 Nov '17

01 Nov '17

Hello, I’m having troubles with running Wind River Workbench. When I try to run it using /opt/WindRiver/startWorkbench.sh it gets frozen during the loading stage. Before that I had to close it because I was not able to save a file because of “Indexing C/C++” dialog that appeared. The server seems to be overloaded especially by the user gabrimi7, who is taking up to 90% of processor. Thanks for a solution. Jiri Kalousek

Remote connection to postel
by Mykhaylo Zelenskyy 01 Nov '17

01 Nov '17

Hi, I have an issue with running Wind River on postel. I connect to postel with "ssh -X zelenmyk(a)postel.felk.cvut.cz" and run WindRiver as "/opt/WindRiver/startWorkbench.sh". WindRiver starts loading, but freezes approx in a half (while there is "Loading Workbench") and after some waiting "Wind River Workbench (on postel)” is not responding." error occurs. It worked few days ago, but was really laggy. My Linux distro is ArchLinux , could it cause any errors? Regards, Mykhaylo Zelenskyy
