Members, I have no /dev/mpp_service too. Does anyone know why?

Members, I have a question, because I can't find any documentation about what is broken or not. Why does /dev/rga not exist in my armbian install? I need it for my FFmpeg rkmpp config.

Hello, I'm looking for armbian 23.8.1 repository on github for building my own image. On github site there is on only the latest and after the 23.08 is more recent one. So where can i download the branche 23.8.1 ?

I finally solve my problem, there was a module called "ssd1307sd" who use the i2c-0 for displaying tty1 (framebuffer). I blacklist it . echo blacklist ssd1307fb > /etc/modprobe.d/ssd1307fb-blacklist.conf And now all is ok.

It was a short-lived satisfaction, the problem resurfaced in the same way after the reboot. # find / -name console /sys/class/tty/console /sys/devices/platform/fe5c0000.i2c/i2c-0/0-003c/graphics/fb0/console /sys/devices/platform/serial8250/tty/ttyS6/console /sys/devices/platform/serial8250/tty/ttyS4/console /sys/devices/platform/serial8250/tty/ttyS0/console /sys/devices/platform/serial8250/tty/ttyS7/console /sys/devices/platform/serial8250/tty/ttyS5/console /sys/devices/platform/serial8250/tty/ttyS3/console /sys/devices/platform/serial8250/tty/ttyS1/console /sys/devices/platform/fe660000.serial/tty/ttyS2/console /sys/devices/virtual/tty/console /dev/console How do i remove the line '/sys/devices/platform/fe5c0000.i2c/i2c-0/0-003c/graphics/fb0/console' which is my OLED display device ? For Usual User this is the result of lsmod without HDMI connected, there is unfortunately nothing about i2c in the modules. # lsmod Module Size Used by sunrpc 364544 1 crct10dif_ce 12288 1 polyval_ce 12288 0 snd_soc_simple_card 20480 0 btusb 69632 0 snd_soc_rk817 40960 1 snd_soc_hdmi_codec 20480 1 snd_soc_rockchip_i2s_tdm 32768 4 btrtl 32768 1 btusb 8821cu 1875968 0 snd_soc_simple_card_utils 32768 1 snd_soc_simple_card btintel 53248 1 btusb polyval_generic 12288 1 polyval_ce hantro_vpu 262144 0 snd_soc_core 270336 5 snd_soc_rockchip_i2s_tdm,snd_soc_hdmi_codec,snd_soc_rk817,snd_soc_simple_card_utils,snd_soc_simple_card btbcm 24576 1 btusb rockchip_rga 24576 0 v4l2_vp9 24576 1 hantro_vpu btmtk 12288 1 btusb snd_compress 28672 1 snd_soc_core ssd1307fb 20480 1 gpio_ir_recv 12288 0 rc_core 57344 2 gpio_ir_recv cfg80211 458752 1 8821cu v4l2_h264 16384 1 hantro_vpu ac97_bus 12288 1 snd_soc_core videobuf2_dma_contig 24576 1 hantro_vpu snd_pcm_dmaengine 16384 1 snd_soc_core bluetooth 819200 6 btrtl,btmtk,btintel,btbcm,btusb snd_pcm 143360 5 snd_soc_hdmi_codec,snd_compress,snd_soc_simple_card_utils,snd_soc_core,snd_pcm_dmaengine v4l2_mem2mem 40960 2 hantro_vpu,rockchip_rga videobuf2_dma_sg 16384 1 rockchip_rga snd_timer 40960 1 snd_pcm rfkill 28672 4 bluetooth,cfg80211 videobuf2_memops 16384 2 videobuf2_dma_contig,videobuf2_dma_sg snd 106496 5 snd_soc_hdmi_codec,snd_timer,snd_compress,snd_soc_core,snd_pcm joydev 24576 0 videobuf2_v4l2 32768 3 hantro_vpu,rockchip_rga,v4l2_mem2mem soundcore 12288 1 snd rk817_charger 20480 0 videobuf2_common 57344 7 videobuf2_dma_contig,videobuf2_v4l2,hantro_vpu,rockchip_rga,videobuf2_dma_sg,v4l2_mem2mem,videobuf2_memops lz4hc 12288 0 lz4 12288 0 zram 28672 3 binfmt_misc 24576 1 sch_fq_codel 16384 6 ip_tables 32768 0 x_tables 57344 1 ip_tables autofs4 45056 2 dw_hdmi_i2s_audio 12288 0 dw_hdmi_cec 12288 0 rockchipdrm 176128 0 dw_mipi_dsi 16384 1 rockchipdrm dw_hdmi 53248 2 dw_hdmi_i2s_audio,rockchipdrm panfrost 77824 0 analogix_dp 45056 1 rockchipdrm drm_display_helper 172032 3 rockchipdrm,dw_hdmi,analogix_dp gpu_sched 36864 1 panfrost display_connector 16384 0 spi_rockchip_sfc 16384 0 sdhci_of_dwcmshc 16384 0 cec 77824 3 dw_hdmi_cec,drm_display_helper,dw_hdmi drm_shmem_helper 20480 1 panfrost drm_dma_helper 20480 1 rockchipdrm drm_kms_helper 208896 8 dw_mipi_dsi,drm_dma_helper,display_connector,drm_display_helper,rockchipdrm,dw_hdmi,analogix_dp drm 651264 12 gpu_sched,drm_kms_helper,dw_mipi_dsi,drm_dma_helper,display_connector,drm_shmem_helper,drm_display_helper,rockchipdrm,dw_hdmi,panfrost,analogix_dp ahci_dwc 12288 0

I solve my problem, I change my distribution from debian bookworm to ubuntu jammy. That's all.

I recently make functionning the I2C-0 port on odroid M1 (thanks to usual user) see topic [odroid m1 i2c not detecting external device]. But I have another problem the tty1 display on the oled screen when I disconnect the HDMI. Where can i disabled this ?

Thank you, your DTB file works. But I have another problem the tty1 display on the oled screen. Where can i disabled this ?

Thank you for your reply.

What pins are activated on the GPIO for i2c0 ?

You're allright, I should see i2c-0 in /dev but the overlay from hardkernel use i2c3 in his rockchip-i2c0.dtbo file. # less /boot/dtb/rockchip/overlay/rockchip-i2c0.dtbo <D0>^M<FE><ED>^@^@^@<DF>^@^@^@8^@^@^@<CC>^@^@^@(^@^@^@^Q^@^@^@^P^@^@^@^@^@^@^@^S^@^@^@<94>^@^@^@^@^@^@^@^@^@^@^@^@ ^@^@^@^@^@^@^@^A^@^@^@^@^@^@^@^Afragment@0^@^@^@^@^@^C^@^@^@^D^@^@^@^@<FF><FF><FF><FF>^@^@^@^A__overlay__^@^@^@^@^C^@^@^@^E^@^^@^@^Gokay^@^@^@^@^@^@^@^B^@^@^@^B^@^ @^@^A__fixups__^@^@^@^@^@^C^@^@^@^U^@^@^@^N/fragment@0:target:0^@^@^@^@^@^@^@^ B^@^@^@^B^@^@^@ target^@status^@i2c3^

I don't know what DT is. I add "overlays=rockchip-i2c0" to armbianEnv.txt
