Hi Padmarao, I am working on a RISC-V bsp variant for the Kendryte K210 and I am also using an included DTB. For my k210 bsp, I changed riscv/shared/start/start.S to set the address of the DTB array before calling bsp_fdt_copy. If we change start.S to handle the following three cases, we would not

Joel, I don't think we need to commit the file now. Some suggestions: - Let's not put RPI2 or RPI3 defines or ifdefs in the file if it's only going to be for the Aarch64 RPI4 BSP - If it will be only used for the RPI4, it might be confusing to have the BCM2836 defines rather than using BCM2711 -

Building RTEMS toolchain on Aarch64 fails on expat

Hi, I tried to use the RSB master branch to build an RTEMS 6 toolchain on a Raspberry Pi 4 running Ubuntu 20.04 64 bit (Aarch64). It fails on expat-2.1.0, with the log saying that expat does not recognize Aarch64. The expat package on the Ubuntu distribution is 2.2.10. Would this be as simple as

Hi, The current RTEMS 6/master branch does not seem to work on the Raspberry Pi single core models, while the 5 branch does. I was able to track it down to a commit where it stopped working: 272534eb725f2486b7a32b39d998202a101bd36e In that commit, the call: /* Clear Secure or Non-secure Vector
