Upload multiple binaries for all cores at once - Spresense board - Arduino IDE
-
Hello everyone,
I started using the Spresense board, and I managed to program all cores following the provided examples through the Arduino IDE. Currently, I need to flash each core separately, one by one.
It's a little time-consuming, so I have a question regarding the possibility to upload multiple binaries for all cores at once: in the manual, it's specified that it might be possible to use a flash_writer tool for such a purpose. Is there any updates and or instructions on how to do it?
Thank you very much for everyone you can help
Best regards,

Hi @Ivan
Unfortunately, this is not possible with the Arduino IDE. The reason is that when you create the firmware (
.spk) for a new core, it overwrites the build of the previous core. This means that there is one.spkfile for only one core at a time. Otherwise you could use the following command to upload multiple binaries for all cores at once:$ ./flash_writer -s -d -n <main spk file name>.spk <sub1 spk file name>.spk ...Best Regards,

Hi @KamilTomaszewski,
thank you very much for your reply, I now understand. What a pity that there is not an easy tool to do it
