Plastic Posted January 18, 2021 Share Posted January 18, 2021 Armbianmonitor: http://ix.io/2MsP 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. 0 Quote Link to comment Share on other sites More sharing options...
hardheid Posted February 11, 2021 Share Posted February 11, 2021 Also facing SPI issues. Trying to flash my laptop using a soic clip connected to spidev1.0 as well as Mizy on spidev0.0. Unlike some others in the forum I was able to activate both successfully. After using flashrom, however, my flashed laptop or orange pi zero won't boot from the SPI chip yet.

Found Winbond flash chip "W25Q128.V" (16384 kB, SPI) on linux_spi. Reading old flash chip contents... done. Erasing and writing flash chip... Erase/write done. Verifying flash... VERIFIED. Same with the Mizy images, write but not working in the end. Could this be the result of a bad buffer? Am I doing something wrong? 0 Quote Link to comment Share on other sites More sharing options...
