Hi all, I've been trying to boot NuttX in protected mode on my ESP32-Wroom board, but I'm running into a few issues unfortunately.
Below is a small excerpt taken from my Ubuntu (running on a VMWare workstation) illustrating the commands I am currently using in order to try and flash the board. root@vagrant:~/nuttxspace/nuttx# ./tools/configure.sh -l esp32-devkitc:knsh root@vagrant:~/nuttxspace/nuttx# make -j4 root@vagrant:~/nuttxspace/nuttx# esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 write_flash 0x1000 ../esp-bins/bootloader-esp32.bin 0x8000 ../esp-bins/partition-table-esp32.bin 0x10000 nuttx.bin 0x90000 nuttx_user.bin This, however, leaves the board in an unusable state - the flashing is successful, but a fault is triggered at boot time. I'm attaching a .txt file to this email with the complete error dump. Could someone please explain what I am doing wrong? Thanks, Robert
