<mjourdan> Darkmatter66: Please try the following patch: https://drive.google.com/file/d/1XEqbksQO_8vXGzVWphgIwfJ1FOeibT0K/view?usp=sharing
<mjourdan> On my end I get u-boot display followed by kernel fb_console on the c2

<Darkmatter66> mjourdan, the patch works on my board too, it shows the u-boot prompt but I haven't tested the smooth transition to kernel (simplefb support)
<Darkmatter66> mjourdan, one thing I noticed is that writing in the prompt is very slow, probably the u-boot drivers are very simple and slow compared to linux drivers
<mjourdan> Darkmatter66: when I write to the u-boot prompt via uart, the result gets displayed almost instantly on screen
<mjourdan> Haven't tested yet with a usb keyboard plugged to the board, is that what you're using ?
<Darkmatter66> mjourdan, no I write through Uart also
<Darkmatter66> mjourdan, it's very prominent if i copy and paste something a bit long
<Darkmatter66> keyboard doesn't work on u-boot for me
<mjourdan> (I'm not even sure if gxbb/usb is in u-boot, haven't checked and memory is blurry)
<mjourdan> mmh can't reproduce, even copy pasting something big is quite fast
<mjourdan> if you type "help", does the display scroll fast ?
<Darkmatter66> mjourdan, I copied a string of around 248 characters and pasted it in u-boot
<Darkmatter66> mjourdan, let me check

<Darkmatter66> mjourdan, the help command scroll fast
<Darkmatter66> mjourdan, I rebooted the board and I can't reproduce the slow scroll anymore !
<Darkmatter66> mjourdan, another issue i get now is that if i copy and paste something long into the Uart it get's cut to around 69 characters
<Darkmatter66> mjourdan, don't know if this is related to the video support though
<mjourdan> Darkmatter66: it gets cut on your serial console or on screen ?
<mjourdan> try pressing a key and see how far you can go
<Darkmatter66> mjourdan, it get's cut on both the Uart and the screen
<Darkmatter66> pressing a key doesn't produce the issue
<Darkmatter66> the issue only happens when copying and pasting
<Darkmatter66> mjourdan, vendor u-boot doesn't have the issue
<mjourdan> I use minicom and can't reproduce, copy pasting a long line gets through fine :/
<Darkmatter66> mjourdan, the length limit is unpredictable (if the string contains some white spaces the limit is arround 69-71 chars, if the string doesn't contain white spaces I can paste up to 104 chars)
<Darkmatter66> mjourdan, I'm using picocom, let me try minicom

<mjourdan> either way, I don't think I can be of much help with that.. at least display is working on gxbb now, I'll post the patches this week
<Darkmatter66> mjourdan, ok minicom show the same problem, anyways, thanks for you help, I will do more testing when the patch is merged and maybe send a patch to enable video by default on p200 boards

<Darkmatter66> narmstrong, Are you talking about the Uart issue or the keyboard not working ? if it's about the Uart issue i don't understand how the Uart is related to USB
<Darkmatter66> mjourdan, sure, Mohammad Rasim <mohammad.rasim96@gmail.com>
<mjourdan> Darkmatter66: I think you hit "reply" instead of "reply all" :D . But thanks for the tested-by
