How to enable av output on bpi-m1+

Hi guys, i just bought m1+ and i can’t activate av output how can i do it? and what os image should i use (i downloaded ubuntu and there is nothing on the av output)?

In case the image you downloaded relies on kernel 3.4 you have to tweak settings in a so called fex file and later replace script.bin. A simple google search for ‘av out script.bin’ should do the job. With mainline kernel things work different.

So, the first thing would be to check which kernel you use.

Thanks for the link. very helpfull! :grinning:

One more question, does AV starts to work immediately after i turn on the power supply or need to do any additional actions? i changed script.bin but still nothing on av port

Don’t know. The M1+ tries to be a 1:1 clone of Banana Pro but maybe some things don’t work there as expected.

It’s hard to tell without a serial console attached (not the answer you wanted to get, I guess?). But that’s the next step. You should start reading here to get an idea how to do this and what’s the status of your device:

Thanks again i’ll try it

Another alternative would be to use an image that is known to work perfectly:

If you want an Ubuntu with GUI try Legacy/Trusty. Banana Pro and M1+ should be very similiar (with one known exception you can find in Link above) but maybe there are other differences as well: BPI M1+ UART3 (TTYS2) not Working (this is also a perfect example for what you can expect regarding support from @sinovoip: NOTHING, they usually post “give us some time” and nothing will happen)

An appropriate fex file for the M1+ you might find somewhere deep hidden in one of the many useless, moronic @sinovoip github repos. Maybe here or maybe there maybe somewhere else.

Their moronic ‘development’ style prevents them from sending their hardware descriptions in a useable form where they should end up and where everyone can find them: (but they don’t send their stuff to the linux-sunxi list but instead clone every few days other github repos to hide somewhere inside important stuff)
