Firmware version 1.05 is released. In addition to the most significant update, which is the support for the little core (C906@700MHz), the wiringX library is also ready. Grab your DFRobot sensors and start playing with them!
Can OpenSBI boot the dual-core system?
Answer: FSBL initiates the boot process; it does not go through OpenSBI. @AnonymousUser1: FSBL itself already supports dual-core startup, and you can use kernel remoteproc to start the small core’s ELF. @AnonymousUser2: BL2 will first load the FreeRTOS binary from the flash into memory and start the small core. After that, BL2 loads OpenSBI/U-Boot/Kernel to run on the big core. @AnonymousUser3: I previously learned that you can bundle the loader for the small core into the fast_image_mcu region of fip.bin (not exceeding 24k). In this case, during startup, the small core will load this part of the program.
