In my design I have not connected VRA1 and VRA2. I have seen several designs that didn’t neither. Do they need ghe resistor/capacitor connections?

Hi there,

I thought with all this knowledge in this forum it would make sense to ask here.

I designed my own custom f1c200s board and the issue is that it unreliable when booting. I can read the SPI NOR in FEL without any issue.

U-Boot 2023.04-rc4 (Mar 17 2023 - 21:26:23 +0800) Allwinner Technology

CPU:   Allwinner F Series (SUNIV)
Model: Allwinner F1C
DRAM:  64 MiB
Core:  27 devices, 15 uclasses, devicetree: separate
WDT:   Not starting watchdog@1c20ca0
MMC:   mmc@1c0f000: 0
In:    serial
Out:   serial
Err:   serial
Net:   No ethernet found.
Hit any key to stop autoboot:  2

The board boots until here, most of the time freezing at „stop autoboot: 2“ not counting down further. Rarely it goes down to zero.

Do you have any idea what could be the reason?

I checked the voltages and they are fine. I also added capacitors close to the f1c200s but that doesn’t change much.

Do you have a hint where to look at? Might it be unstable power? A problem with the crystal habing wrong capacities?

I guess I can rule out a SPI NOR issue by downloading u-boot with SPL directly to DRAM.

Let me know what you think. I can upload my schematics of course.

Could you elaborate a bit more on where the advantages are compared to the other bare metal xboot versions available for the f1c100s?

Can the user set the boot logo?

Happy to see lvgl6 running on the f1c100s. If you continue working on it, I would highly appreciate if you could share updates.

Wow, great project. Thank you very much for sharing the latest version.

Hi everyone,

I'm a fresh owner of the Lichee Nano and I wondered how to compile and use RT-Thread on it.


I checked out rt-thread v5.0.2 on git but I run into issues.

Several howtos tell to run "scons --menuconfig" but it seems this command is not available anymore. Could someone guide me in the right direction?

Here is the error when trying to run menuconfig:


>scons --menuconfig
scons: Reading SConscript files ...
Newlib version: 4.1.0
scons: done reading SConscript files.
usage: scons [OPTION] [TARGET] ...

SCons Error: no such option: --menuconfig

Thanks for sharing!

Could someone tell if this is the newest version available or point to a newer one?

Best, rose
