I2C PINOUT REFERENCES

ON VIM3L there are 2 I2C port, but…
this pinout
22|PIN.A15
23|PIN.A14
I cannot find on S905D3 datasheet, in fact PINA from pinA0 arrives only to PINA11, not more upper,
only works I2C on port 25/26

could you check about i2c descriptions in VIM3L i2c docs?
thanks.

noone answers about?

What you mean about this ?

you define i2cm3 on PIN-A14 and PIN-A15, but on datasheet I cannot find them, seems that PIN-A, arrives only til PIN-A11, or maybe I’m wrong, but if there are not PIN A14 and PIN A15, how is possible to have i2c on that you suggest for i2cm3 PINS?, also becouse i2cm3 (declared into proper enc file) is not working, while I2CA0 works as expected.

Why not have ? https://dl.khadas.com/products/vim3/datasheet/a311d_datasheet_08_wesion.pdf

Which image you used? I checked latest image works well: https://dl.khadas.com/products/vim3/firmware/ubuntu/emmc/vim3-ubuntu-20.04-server-linux-4.9-fenix-1.4-221229-emmc.img.xz

uhmmm… image I have fenix (1.4) with 6.1 kernel, by oowow tool… and doesn’t work, but maybe I have read wrong datasheet pdf… I’ll have to check… both…

Please check with the 4.9 kernel image.

I’ll try but seems that with 4.9 kernel all works well, instead with high kernel, some functions seems to be lost…
