Both PSRAM layouts were mapped as a single RWX window, so everything in external
RAM - the heap included - was executable.
PSRAM used as data only is now RW, and under XIP-from-PSRAM it is split per
section as ESP32-P4 does: .text RX, .rodata read-only, and the MMU-page
alignment gaps and the reclaimed heap RW, so neither is executable.
Both describe the layout that esp_psram_init() produces, and the entries are
locked, so - again as on ESP32-P4 - they are only narrowed when
CONFIG_SPIRAM_PRE_CONFIGURE_MEMORY_PROTECTION says that layout applies. Without
it the application owns the region and PSRAM stays RWX.
The per-section entries cost one PMP entry more than the 16 available, so the CPU
subsystem and peripheral windows are chained as TOR entries, taking one entry
instead of three.
soc.h is corrected against the S31 bus address map: the peripheral window base
was 1 MB too low, and the LP peripheral top, derived from a register base plus a
size rather than from the map, was 16 KB short. SOC_NON_CACHEABLE_OFFSET_FLASH
is added.
The generated assembly emitted <name>_length immediately after the raw
payload bytes, so the 32-bit word landed misaligned whenever the data
size was not a multiple of 4. Consumers declare it as a 32-bit object
(e.g. `extern const size_t <name>_length` in the ULP firmware loaders),
so the compiler emits an alignment-assuming word load, which is a
misaligned flash read prone to spurious load faults on chips with
SOC_CPU_MISALIGNED_ACCESS_ON_PMP_MISMATCH_ISSUE (ESP32-C6/H2/H21).
ldgen skips regeneration when a fingerprint over the section names, the
linker fragment files, sdkconfig and Kconfig is unchanged. The linker
script template was not part of that fingerprint, even though everything
outside its mapping placeholders is copied into the generated script
verbatim.
The build system regenerates the preprocessed template whenever any of
its inputs changes, not only when a linker fragment changes. When such a
change reaches ldgen but leaves the section names alone, the fingerprint
still matches, generation is skipped, and the image is linked against the
previously generated script. The skip path updates the mtime of the
output, so nothing in the build output shows that the change was dropped.
Add the template to the fingerprint so that regenerating it always
regenerates the linker script.

Trim bootloader size by moving some logs to DEBUG. Allows
compiling bootloader on P4 with CONFIG_ESPTOOLPY_FLASHMODE_QIO
without changing partition table offset
On some Windows systems, antivirus, endpoint-security or DLP/encryption
software intercepts short-lived toolchain processes and strips their
stdout when the build captures it through a pipe, while the same command
prints its output normally when run by hand. The tool exits successfully
but returns nothing, and each build step that reads toolchain output then
failed with a different, cryptic error far from the real cause:
- CMake configuration aborted with "Unknown arguments specified" in
components/xtensa/project_include.cmake, or "check_expected_tool_version
invoked with incorrect arguments" in components/esp_common.
- ldgen turned the empty objdump output into an opaque pyparsing
"Expected 'In archive'" traceback.
- idf_tools.py silently reported the compiler/debugger version as
"unknown", sending users into a fruitless reinstall loop.
Detect the empty result at each consumer and fail (or warn) with an
actionable message that names the likely cause and the remedy:
- tools/cmake/compiler_query.cmake: new __compiler_query() helper runs a
compiler query and fails with a clear error on empty or failed output.
It is a standalone module included by both the cmakev1 and cmakev2
utilities, since the esp_common and xtensa project_include.cmake that
call it are shared by both build systems. The xtensa if() arguments are
now quoted so an empty result no longer collapses into a parse error.
- tools/ldgen/ldgen.py: _run_objdump() rejects empty objdump output, and
non-empty-but-unparsable section info is caught and re-raised as a clear
LdGenFailure instead of a raw pyparsing traceback.
- tools/idf_tools.py: empty version output now warns with the cause and
returns UNKNOWN_VERSION instead of silently reporting "unknown".

FastMCP was renamed to MCPServer in mcp 2.0, which made idf.py mcp-server
report a false "MCP dependencies not available" error. Prefer MCPServer
and keep a FastMCP fallback for mcp 1.x.
