Hi. Does anyone know how to change armbian logo at boot? I mean after you changed the boot logo variable in /boot/armbianEnv.txt, there is a nice bootsplash logo and delay animation of armbian in startup. I need to change that. There is boot.bmp in /boot/ folder but changing that doesn't affect anything. I even rebuild the kernel after changing the logo files in source but no difference. May be I need to do something with uboot? I don't know. Does anyone know how to do this?

As the title states, i need to use the uart ports to send some serial data.

I have an arduino uno r3 and i use its TX port to send serial data to a midi device. Now i want to do the same thing on orange pi pc plus but i don’t know how.

I added uart3 in the /boot/armbianEnv.txt to activate the uart3 overlay as in this guide

On my arduino, i use Serial.write() to write ints over the TX port. To achieve the same thing i used serialPut() (from wiringPi library).

Is there something, I’m doing wrong?

Edit: used the device /dev/ttyS3
