### Description
Hello world :-)
I just got ESP32-P4-Nano board from WaveShare. Nano board [1] seems to be
schematic compatible with ESP32-P4-Function-EV-Board [2], so for start I tried
to build and run existing Function board firmware. Nano uses GPIO 37,38 TX,RX
pins over CH343 chip to USB-C.
I noticed that build is a bit picky about the compiler. I am using
`CROSSDEV` parameter to make to select build toolchain.
* builds fine even with old espressif's idf tools riscv32-esp-elf-gcc
version 8.4.0.
* builds fine with xpack-riscv-none-elf-gcc-14.2.0-3-linux-x64 as
recommended in the docs [3].
* It does not build with system riscv64-none-elf-gcc 11.3.0 (throws `error:
unknown type name '_LOCK_T'` errors).
Tried `gmake flash` with esptool version:
1. 4.10.0:

And then I have boot loop like this no matter what compiler and esptool is
used:
```

What do I miss? Any hints welcome :-)
