Replace raspi zero w with Radxa Zero

#1

Hello, Radxa team.
I’d like to strongly replace the raspi zero w with Radxa Zero due to 32bit weak power. I also need two PWM and some gpio function. However, I could not implement PWM capability. I could not find overlay file (probably like pwm-meson.dbto).

Now I’m using the Zero with 512MB and kernel 5.10.72-meson64. And I can manipulate /sys/class/pwm/pwmchip0,pwmchip2 using shell command. But no pwm signal appears from any gpio pin.

Thank you for your support.

Mmmm… I did not test the gpios so far. I am just commenting to keep this alive.

Hi,
I got two PWM signals thanks to the Radxa team, then please see below,

Thanks.
