Contents
Prerequisites
- PTN3460 Programming Guide
- EDID config (128 bytes)
- i2c-tools installed
sudo apt update
sudo apt install i2c-tools
Step-by-step procedures
(use EDID 6 and panel G070VW01V0 as example)
On Ubuntu
create the setup script from EDID config
EDIDNEW=6
EDIDBIN=g070vw01v0.bin
SCRIPT=~/set_edid_${EDIDNEW}.sh
REG81=$(printf "0x%02x" 0) # Please refer to the PTN3460 Programming Guide to set correct value
REG84=$(printf "0x%02x" $((2*EDIDNEW + 1)))
REG85=$(printf "0x%02x" $EDIDNEW)
echo -e "REG81:$REG81\nREG84:$REG84\nREG85:$REG85\n"
cat << EOT > $SCRIPT
#!/bin/bash
i2cset -f -y 2 0x20 0x85 $REG85 b
$(
xxd -c 16 -ps $EDIDBIN |
sed "s/../0x& /g; s/ *$//" |
for ADDR in `seq 0x00 0x10 0x70`; do
read
echo i2cset -f -y 2 0x20 `printf "0x%02x" $ADDR` $REPLY i
done
)
i2cset -f -y 2 0x20 0x81 $REG81 b
i2cset -f -y 2 0x20 0x84 $REG84 b
i2cset -f -y 2 0x20 0xe8 0x01 0x78 0x45 0x56 i
EOT
chmod +x $SCRIPT
run the script and reboot
sudo $SCRIPT
sudo reboot
On U-Boot
Press any key to stop auto boot, and set matched device tree overlay (dtbo)
- Multi-display (HDMI + LVDS)
- The LVDS is always major display that has nothing to do with the specified order.
setenv DISPLAY hdmi.dtbo lvds6.dtbo
saveenv
reset
- LVDS only
setenv DISPLAY lvds6.dtbo
saveenv
reset
Appendix
fetch the EDID config
(use the pre-set EDID 2, panel G070VW01V0, as example)
EDID=2
EDIDBIN=g070vw01v0.bin
sudo i2cset -f -y 2 0x20 0x85 $EDID b
for DA in `seq 0 0x10 0x70`; do
sudo i2cget -f -y 2 0x20 $DA i 0x10
done | xxd -r -p > $EDIDBIN
