Hello,
first post here, so sorry if did not provide enough information. I need to change spi buffer length to 8192. So far tried:
1) modprobe spidev bufsiz=8192
creating the file /etc/modprobe.d/spidev.conf and adding to it the line "options spidev bufsiz=8192"
When I do "cat /sys/module/spidev/parameters/bufsiz", it gives me "4096".
2) Add to /boot/cmdline.txt:
spidev.bufsiz=8192
When I do "cat /sys/module/spidev/parameters/bufsiz", it gives me "4096".
3) cd /sys/module/spidev/parameters
chmod 666 bufsiz
echo 65536 > bufsiz
did nothing.
4) /boot/armbianEnv.txt
added options spidev bufsiz=8192
When I do "cat /sys/module/spidev/parameters/bufsiz", it gives me "4096".
I don't know anything else what to try. Is it possible.
