Typically, there's no need to rebuild your project from the ground
up. Instead, simply enter the Maixduino
package URL in the Additional Boards Manager URLs
section.
However, when needed, Maixduino Github
repository offers open-source resource that you can utilize as a
foundation for further development.
The W

comprehensive course content, serving as an excellent tutorial for those
interested in following along.

2.2.3 Bricked
Unfortunately, my QuickFeather
is bricked. Whenever reset or even
entering user mode, the LED on QuickFeather
turns to red in the end.
In my test, no matter MicroPython Download
RPI_PICO is dragged-and-dropped, or a customized
program is uploaded via Arduino IDE as in the following
picture:
I got the solution from my posted issue Boot
from eMMC or NVME? Existing Doubts on the official RVspace forum.
The solution is just hidden in the file
/boot/extlinux/extlinux.conf. Well, to modify this file
correspondingly, you need to:
mount /boot using
sudo mount /dev/sdc3 /mnt
take a look at the file
/boot/extlinux/extlinux.conf
➜ extlinux cat extlinux.conf ## /extlinux/extlinux.conf ## ## IMPORTANT WARNING ## ## The configuration of this file is generated automatically. ## Do not edit this file manually, use: u-boot-update

Now, I'm able to boot from both SD card or
NVME, however, there seems to be NO
such a thing similar to grub? And I'll have to
manually edit the value of default l1 accordingly whenever
I want to boot from a different device.
Anyway, I've got to stop here for now. I'll talk about how to build a
fresh distro for VisionFive2
from scratch in my next post.

2. Demonstrate Arduino
Examples
2.1 Environment Configuration
Install Arduino Environment When I tried to run
the basic
example blink, I was asked to install the package
renesas_uno@1.0.5, as shown in the Output console of Arduino IDE:

Please upgrade the firmware Attempting to connect to SSID: TELUSXXXX SSID: TELUSXXXX IP Address: 192.168.1.YY signal strength (RSSI):-52 dBm
3.2 Upgrade Firmware of UNO R4
Wifi
It's confusing that I received the error message Please
upgrade the firmware, right after I installed/upgraded
renesas_uno@1.0.5 from within Arduino IDE.
In the end, I noticed there are 2 main chips on Arduino
UNO R4 WiFi, and renesas's firmware is
installed/upgraded, but ESP32's firmware hasn't yet.
Therefore, I proceeded with upgrading ESP32's firmware
by following Arduino
UNO R4 WiFi Upload to ESP32.
Different from 1.1, by shorting the
download pin and GND, now we have a
different lsusb result:
1 2 3
...... Bus 011 Device 007: ID 303a:1001 Espressif USB JTAG/serial debug unit ......
Again, I was asked to install the esp32 package(s),
as shown:
For LLVM-related variable LLVM_ENABLE_PROJECTS, if
you want to build ALL projects by specifying
-DLLVM_ENABLE_PROJECTS=all, all the following projects
clang;clang-tools-extra;cross-project-tests;libc;libclc;lld;lldb;openmp;polly;pstl
are to be built. Particularly, libc is also to be
built, which will bring me the following error:
1 2

I tried to build Intel Open3D from source, using
GCC/G++ONLY. Of
course, I used ALL 3rdparty libraries either from
default Ubuntu repository, or manually installed the newest version,
rather than using the 3rdparty
libraries coming with Open3D itself.
Today, May 9, 2024, I had this annoying Open3D successfully built
again, with my PR
6788.
