I'm trying to compile an LED display driver: https://github.com/arthur-liberman/linux_openvfd I follow this description: https://github.com/bk3a12/openvfd_enable_for_tx3_mini However, I can't build anything and the whole process ends with errors: sh ./scripts/modules-check.sh /home/user/INSTALKI/linux_openvfd/driver/modules.order make -f ./scripts/Makefile.modpost make[3]: *** No rules to make an object '/home/user/INSTALKI/linux_openvfd/driver/modules.order', required by '/home/user/INSTALKI/linux_openvfd/driver/Module.symvers'.

@werner Sorry the delay, I was trying to get the TTL adapter.

Thank you!

Hi, I also tried to run this sensor, tried different ports but to no avail. maybe you found a way to solve this problem?

Hi! So, I tried this overlay, and the device still did not detect USB. Although when I tried switching the dts file to the topwise a721, the HDMI stopped working but USB devices were correctly detected. On top of that, no the display still does not work even with the topwise device tree. I checked the RAM clock speed with the command you mentioned and it said 432000000, which is much higher than what I found from the boot file from original Android (384000000). Is there a way I can rebuild just u-boot and install it in this working image?
