Tinker Board 2S set SPI buffer size

[sk109sk 0]

Hello!

I want to change the SPI buffer size from 4096 to a greater value.

I tried to put spidev.bufsiz=65536 in /boot/config.txt but it is not working.

Can someone to help me to set buffer size to a larger size?

Thanks!

please add it in /boot/cmdline.txt instead

sudo vim /boot/cmdline.txt

add this line, save and reboot

spidev.bufsiz=65536

you can check the value with:

cat /sys/module/spidev/parameters/bufsiz
