The configured maximum should match each target's fixed LP/RTC
reservations so menuconfig does not advertise values that the linker
cannot support.
Keep the linker failure explicit about CONFIG_ULP_COPROC_RESERVE_MEM
because application RTC sections still share the remaining LP/RTC RAM.
On RISC-V chips with SPIRAM support (esp32c5, esp32c61, esp32h4, esp32p4,
esp32s31), esp_restart_noos() was disabling the cache while the current
stack pointer could still be in external RAM. Any stack access after cache
disable (function call, local variable spill) would then fault with
"Cache disabled but cached memory region accessed".
Xtensa chips (esp32, esp32s2, esp32s3) already had this guard via the
SET_STACK macro. Add the equivalent for RISC-V:
- Add rv_utils_set_sp() to riscv/rv_utils.h (plain "mv sp, %0" with a
memory clobber; no window register management needed on RISC-V)
- In each affected system_internal.c, under
CONFIG_FREERTOS_TASK_CREATE_ALLOW_EXT_MEM, check whether the current
SP is in PSRAM and if so switch it to the top of internal BSS before
any cache disable or writeback operation
- Fix xTaskCreateStaticPinnedToCore() stack size argument in the
spiram_stack test (was passing bytes instead of word count)
- Mark the null-pointer write in func_do_exception() as volatile to
prevent the compiler from optimizing it away
- Extend the [spiram_stack] tests to RISC-V by sharing fibonacci() and
the task/finish helpers across architectures, guarding only the
Xtensa-specific WINDOWBASE/WINDOWSTART prints
Wrap MWDT-related code under SOC_WDT_SUPPORTED so targets without a main
watchdog can compile.
Add SOC_RTC_WDT_SUPPORTED for RTC watchdog usage (bootloader, slow-clock
paths) and regenerate Kconfig.soc_caps.in. Bootloader RWDT setup stays
under SOC_RTC_WDT_SUPPORTED; MWDT flashboot teardown stays under
SOC_WDT_SUPPORTED.
ESP_INT_WDT, ESP_TASK_WDT_EN, and BOOTLOADER_WDT_ENABLE depend on
SOC_WDT_SUPPORTED where applicable. Build xt_wdt.c only when
SOC_XT_WDT_SUPPORTED. Provide no-op panic WDT helpers when
SOC_WDT_SUPPORTED is disabled.
CMakev2's DEFERRED mode for idf_component_optional_requires only links
optional components already present in the dependency graph. This caused
esp_coex headers to be unavailable when building minimal examples on
targets with both WiFi and IEEE802154 (e.g. esp32c5, esp32c6).
Moving init_coexist to esp_coex removes the cross-component dependency
and ensures the init function is only compiled when esp_coex itself is
part of the build. A linker hook is added to guarantee the object file
is not silently discarded by the linker.
