Hi @Laczen: For my RISC-V and Arm64 Ports of NuttX, I mount the ROM FS like this... https://lupyuen.org/articles/avaota.html#mount-the-romfs ```c struct boardioc_romdisk_s desc; desc.minor = RAMDISK_DEVICE_MINOR; desc.nsectors = NSECTORS((ssize_t)__ramdisk_size); desc.sectsize = SECTORSIZE; desc.image = __ramdisk_start; int ret = boardctl(BOARDIOC_ROMDISK, (uintptr_t)&desc); ``` __ramdisk points to a Memory Region defined in the Linker Map: https://lupyuen.org/articles/avaota.html#linker-script ```c /* Linker Script: We added the RAM Disk (16 MB) */ MEMORY { dram (rwx) : ORIGIN = 0x40800000, LENGTH = 2M pgram (rwx) : ORIGIN = 0x40A00000, LENGTH = 4M /* w/ cache */ ramdisk (rwx) : ORIGIN = 0x40E00000, LENGTH = 16M /* w/ cache */ } /* We'll reference these in our code */ __ramdisk_start = ORIGIN(ramdisk); __ramdisk_size = LENGTH(ramdisk); __ramdisk_end = ORIGIN(ramdisk) + LENGTH(ramdisk); ``` And I copied the ROM FS, from the NuttX Image into the above Memory Region: https://lupyuen.org/articles/avaota.html#copy-the-romfs Would this work for ESP32? -- This is an automated message from the Apache Git Service.
