Hello, I get the NamerError when I try servo control on the Jetson Xavier nx series using pwm. The motor does not turn. nothing happens. The full trace is pasted below. Motor attached to pin 32. The python function is also provided below. How can I resolve this? or what am I doing wrong? Note: If i…

let’s close this thread and follow-up Topic 200639 .

hello user105768, you may skip flashing the board by just download the JetPack release image to your host machine to obtain all the necessary tools, binaries. you must re-flash the target if you process to modify pinmux spreadsheet, to apply the cfg file settings. the flashing process will erase …

well, since the main goal at this moment is to have at least one pwm pin. since most of my other software was based on jetpack 4.5.1 I will use this again. where are the steps in order for me to do this using an external linux pc? I will connect the jetson to the pc, then try to modify pinmux sprea…

@JerryChang how are you? I marked pin 32 and 33 as pwm customer usage and output for direction on the pinmux table in excel, generated the gpio, padvoltage and pinmux dsti files. got two .cfg files using the tool: one .cfg file from the gpio and pinmux dsti files and another .cfg file from the padvo…

[image] user105768: Now what do I do next so that i can flash the jetson with these two files to have pwm configured for the gpio header pins? hello user105768, after you create the cfg file by pinmux-dts2cfg.py, you should perform flash script, flash.sh to update the image. please also che…

hello, which flash.sh script? I am seeing about 4 files ending in flash.sh. Also where do I place my configurations file after creation? Which lines of p3668.conf.common do I modify. I guess: PINMUX_CONFIG=“tegra19x-mb1-pinmux-p3668-a01.cfg”; is for the file generated using pinmux and gpio dsti…

hello user105768, it’s PMC_CONFIG, normally it should be same as default files. the flash script is under installation folder, i.e. $OUT/Linux_for_Tegra/, you may also check Basic Flash Script Usage to re-flash the target manually.

oh, so to flashmy jetson with storage on sd card or emmc, I execute the script as: sudo ./flash.sh p3668.conf.common internal or is it supposed to be: sudo ./flash.sh jetson-xavier-nx-devkit internal This part is not yet clear to me. Thanks

hello user105768, p3668.conf.common, it’s a common file to define all default configurations. please use the jetson-xavier-nx-devkit-***.conf to execute the flash process, it depends-on which DevKit storage you’re using. thanks

I see. There is an autoflash script which apparently figures out the board automatically? Why dont I use that? Whats the difference between the two? It is also in the same directory as the flash.sh. Since i have only one board, can I just run that after connecting my device in recovery mode to the p…

I have a jetson xavier nx developer kit with an on module SD card.
