RaspberryPi OS 64-bit

natzguk

Hi I am on 64-bit Raspberry Pi 4B

Operating System: Debian GNU/Linux 12 (bookworm)
Kernel: Linux 6.1.0-rpi6-rpi-v8
Architecture: arm64

Unfortunately I can not use VEYE-MIPI-X I2C.sh since i2c_read and i2c_write are only for 32bit. Is there any support for 64-bit planned?

veye_xumm

@natzguk Hello, these two programs are written in C language, and the source code is provided in the directory. You just need to recompile them.

newleaf

@veye_xumm For anyone else. This works perfectly. Note that when recompiling on 64-bit Pi, the following warning is produced. It still builds. Just copy the outputs to bin and the scripts work fine.

./make.sh
