New to zynthian but i need some help with a basic setup


#1

hi guys

ok so I bought a raspberry pi3 and downloaded the rightfull image burnt it to a sd card and while I try boot it all I get is a lightning type icon on the top right of the screen

im using hdmi

raspberry pi3

I downloaded the right image file , 4gb and burnt it to a 8gb sdcard

what im I doing wrong?


#2

The lightning icon tells you that there is something wrong with power supply, it’s not zynthian related, it’s an hardware indicator.


#3

OK I got a psu and now I just get a black screen after the loading…


#4

Those images are tailored to a very specific hardware setup: RPi + PiTFT display + HiFiBerry DAC + encoders board.

Have you changed all the configuration files to use HDMI display and touch instead of TFT display and encoders?

Moreover, don’t hope to get something useful without a DAC. Internal sound is useless and USB audio cards are a pain in the arse.


#5

it was more of a test to see if it I could get it working as is, ill keep getting more bits and pieces until ive got the full kit


#6

Yes… been there, done that (while waiting for PiTFT and HifiBerry shipping)

With just a plain (no touch) HDMI display and no DAC, if you make those changes to config files, you’ll get a perfect deaf and mute zynthian… :slight_smile:


#7

There is this thread . . …

The only thing to be aware of is that the directory structure has changed a bit so if things ain’t where they claim to be on the thread they’ve probably just moved somewhere that is a bit more sensible in retrospect.

RB-TFT3.2-V2 can this tft be used with zynthian


#9

#10

Looks like a waveshare32. But quite expensive…


#11

its a touchshield… im not bothered about the price really, just need to be able to use it and get it quite fast here, im in finland and this company will deliver in a few days etc


#12

Maybe they are compatible. Just saying that I would google for waveshare and try to get that. Looks like a waveshare clone to me.


#13

it looks like a clone yes, I just ordered it, few days to come ,


#14

Hi @christianforshaw!

Please, it would be a lot better if you use the last image:

There is no “gorgonilla version” (lite), so you will need a 16GB SD card.

Regards,

@jofemodo
I sent you a few pm about spares I need if you have them for sale still


#16

i just sent you the answer :wink:


#17

ok so my hifiberry dac came and my tft

its a joy-it 3.2" touchscreen tft

tried pluging the tft in and all I get is a white screen, the same white screen as if nothing is installed on the raspberry

I plugged my hdmi monitor in at the same time and I get the loading text message screen thing, nothing else


#18

Search for waveshare32 in this forum. You need a special wiring.


#19

is it a different wiring or should I edit the config file

I search this

Some settings may impact device functionality. See link above for details

Tell bootloader to use initram image

Load RT Kernel for RBPI2

#kernel=kernel7-rt.img

uncomment if you get no picture on HDMI for a default “safe” mode

#hdmi_safe=1

uncomment this if your display has a black border of unused pixels visible

and your display can output without overscan

#disable_overscan=1

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

uncomment to force a console size. By default it will be display’s size minus

overscan.

#framebuffer_width=1280
#framebuffer_height=720

uncomment if hdmi display is not detected and composite is being output

#hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

#hdmi_group=1
#hdmi_mode=1

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

#hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

#config_hdmi_boost=4

uncomment for composite PAL

#sdtv_mode=2

No, there is a thread in this forum which tells you what you have to do. I don’t have time to search it right now.
