I am using LYRA Board with Ubuntu_Luckfox_LYRA_MicroSD_250417 image.

When I run LuckFox-config, USB is not in the menu, just SPI + I2C + UART ...

The Usb-A interface is sitting on the board unused.

I tried booting with power to VSys = 5V.

I am using a small SD to USB Adapter ( with a 4GB ...

Pretty sad lack of support here for your chips.

* adafruit-circuitpython-sdcard - does Not work.
* Spi-fat-fuse - does not work.
* dts file format for spi - does Not work.

What does work on these boards ???

These chips really don't provide much to work.
Using LuckFox Pico Mini :

I tried DTS :

SPI is enabled on :
SD CS -> G48
SD SCK -> G49
SD MOSI -> G50
SD MISO -> G51


vi spi-bitbang-sd.dts


/dts-v1/;
/plugin/;

/ {
compatible = "brcm,bcm2835"; // Change for your specific board ...

see below

Can you please give instructions on how to mount /dev/mmcblk0 for spi0.0 on Lyra board

I tested the code below :


vi test_sdcardos.py

import os , sys
from periphery import SPI

# Open the SPI device :
spi = SPI("/dev/spidev0.0", 0, 1000000)
print("spi=" + str(spi))

sd_device_0 = "/dev/mmcblk0p1" # Typical SD node in Linux
sd_device_2 = "/dev/mmcblk2p1" #
mount_point = "/mnt ...

# ls /dev
block mmcblk1p1 rve tty30 tty6 vcsa6
char mmcblk1p2 shm tty31 tty60 vcsu
console mmcblk1p3 snd tty32 tty61 vcsu1
cpu_dma_latency mmcblk1p4 spidev0.0 tty33 tty62 vcsu2
disk mmcblk1p5 stderr tty34 tty63 vcsu3
fd mmcblk1p6 stdin tty35 tty7 vcsu4
full mmcblk1p7 stdout tty36 tty8 vcsu5 ...

I want to mount a 2nd SD Card (by using the SPI bus) to have a removable SD Card,
considering the main SD Card is the Boot device and not removable.

Howto go about this ?

So how do I get gcc ?

I give up with this chip / board.
The support for this chip /board is minimal / not existing.

- no gcc
- no apt update cmds
- Can't even find any documentation on Pin functions - such as which pins are SPI / I2C -

Luckfox Doc (including 3566) webpages specify to use Upgrade ...

I Firmware flashed :
Luckfox_Lyra_Zero_W_Flash_250717_MaskRom-SpiNand\update.img

Which got me to adb shell.

I booted off of both firmware & SDcard: Luckfox_Lyra_Zero_W_MicroSD_250717_BuildRoot/update.img
- but No apk-get cmds
How am I supposed to get Wireless Updates ?
