Can we start with the assumption that Simplicity Studio 5 has been installed along with the relevant SiSDK (currently 2025.6.1)?
Or despite Simplicity Studio 6 being in Beta work with that? It supports VSCode as well… (Same SiSDK).
“We” can then build out the necessary steps to build a Matter device, viz Light, starting with “internal” bootloader and later using the “external” (SPI flash) bootloader for OTA?
