That really sucks. There is no way to make audio work besides this? I like the idea of being able to “hot swap” my card.

Hi,
I tried the ubuntu image.
root@luckfox:/# lsusb
Bus 001 Device 003: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Seems more sophisticated.
I will check dmesg. one moment…
You can make a external sound card and connect it to picocalc via gpio near the screen.
Audio output via soft pwm does not need hardware modification, but currently it has a very loud noise. If rockchip shares more document about rk3506’s cortex m0 core, I may use the m0 core to output soft pwm and get better sound quality.

Hi, I uploaded a new boot.img to google drive.
You can try it
adb push boot.img /tmp
adb shell
dd if=/tmp/boot.img of=/dev/mmcblk0p2 bs=1M
reboot
then load the wifi driver

So there is no way to remap the pins in software?
Ok, I try it.

GPIO4_B3 and GPIO4_B2 are not rmio pins. They can not output hardware pwm.

I suppose I could change the header pins on the Lyra to pin through and not solder those two pins to the board but bridge them over the device.
GPIO4_B3 and GPIO4_B2 are 1.8v pins. Other RMIO pins are 3.3v pins. Be careful if you just solder them together.
If you have any ideas about improving audio via soft pwm, the source code is on github.

It seems that ralink firmware is missing. You can download it from here:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rt2870.bin
maybe place the file under /usr/lib/firmware or /lib/firmware would work
Also I forgot to mention that udhcpc -i wlan0 should be executed after wpa_supplicant

It have now worked!! Thanks!!
Was it hard to find the kernel modules for this USB Stick?
Could you please provide a Image for this?
I am not that good in compiling images myself.
Could it be more about voltage than pwm? Sorry, I’m a bit of a novice here.
New image uploaded, including rtl8188fu and rt2800 wifi drivers.
A script, called wifi-up.sh and a config file, called wpa_supplicant.conf can be used to setup wireless network.
wget will ignore ssl certificate checks by default. This will fix “Could not Connect to BBS” error of pico-8 splore.

Ok,
I have the RT5370 and seems still be available.

Hi,
Maybe you have thought of this already:
I have found that pin 35 is labeled ADC_VREF on the Raspberry PI Pico and on the LYRA as not connected (NC). When i measure the the voltage in the Raspberry i get 3.3 Volts. On the Lyra there is nothing. Only speculation on my side, but could this be the reason why on lyra the ADC is not working properly because of the missing reference voltage? Maybe bridging the pin 36 and 35 on the lyra can to the trick?
this is also interesting:
