Arm64 port of xtensa-esp32-elf and esp-idf

[syseng]

I am doing development on Raspberry Pi 4 with 64bit OS.

I used crosstool-NG to build xtens-esp32-elf. I setup a web server to to serve that asset. but when I run ./install.sh it grabs esp32 but fails on esp32s2 esp32s3, riscv, esp32ulp-elf esp32s2ulp, and openocd-esp32.

Do I need to make each one of the packages for the arm64?
Can I contribute the to ESP ?

Hi,

Thank you that suggestion, I am already developing on a 4G RPi4 using the 32bit system. I am using RPi GPIO pins to control ESP32 reset and GPIO0 pins. No wires change to switch from run to flash to run.

I am trying to rebuild esp-idf using aarch64/arm64. I have compiled xtemsa-esp32(s2/s3)-elf, working on getting riscv, binutils and openocd compiled on arm64.
