I added https://nutcracker.pine64.org/arduino/package_bouffalo_index.json (Also tried index.json directly from github). But, the Arduino IDE throws me :
Some indexes could not be updated. Get "https://nutcracker.pine64.org/arduino/package_bouffalo_index.json": remote error: tls: internal error: https://nutcracker.pine64.org/arduino/package_bouffalo_index.json

In #4 I described the problems I had with uploading programs to the PineCone. I needed to add #!/usr/bin/python3 and convert the file encoding to be able to execute the python script bl602-flasher.py. But now I get the following error message when trying to upload code form the Arduino IDE:

Traceback (most recent call last):

Does anyone know how to modify the script to fix this error?

I added https://nutcracker.pine64.org/arduino/package_bouffalo_index.json and did the install in board manager but the only board found is PINE64 Pincone could not find Ai-WB2-32S or anything with bouffalo or anything other than PINE64 Pincone

I am curious if this project has been abandoned or if there is interest in expanding to include additional cores (bl808)?

Trying to upload the Blink.ino to the Pine64 BL602 EVB ver1.2 on my M1 Mac I get the following messages:

Any file I try to compile fails with the error:

I'm using version 0.0.1 of the Arduino core on a MacBook Pro, with Arduino IDE 1.8.13.

Can anyone suggest a solution?

Does this work with the Bl702 mcu?

ENV: ubuntu 20.04, python3.8

1. compile: no execution permission, chmod +x
2. update: get_contrib_path() return wrong path. (bl602-flasher.py)
3. change serial with pyserial(for python3.8) (pip3 remove serial, pip3 install pyserial)
4. force using python3, such as #!/usr/bin/python3,

I have a problem uploading my code. I already changed the permissions of the executable files, but now I'm getting the following errors:

Compiling does work but when I try to upload the code the cursor changes to a crosshair, probably I have to select a window or something. Is there a way to fix this?

The binaries of the toolchain for Linux (riscv64-unknown-elf-linux-0.0.1.zip) have bad permissions and require some modifications from the user. They don't have the executable bit.

These binaries are located in:

• riscv64-unknown-elf/0.0.1/bin/
• riscv64-unknown-elf/0.0.1/riscv64-unknown-elf/bin/
• riscv64-unknown-elf/0.0.1/libexec/gcc/riscv64-unknown-elf/8.3.0/

Thanks to @9names for pointing me these paths.

As the purpose is, I think, to simplify things, it might be better to change the permissions in the downloaded archive.

I don't know if MacOS is also impacted, and I suppose that Windows isn't.
