pthread_rwlock_timedwrlock is not implemented and will always fail (IDFGH-15461)

Hi @keyflux! Thank you for the report. The current status of [POSIX Threads support](https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/system/pthread.html#read-write-locks). Yes, the [pthread_rwlock_timedwrlock()](https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_timedwrlock.html) is not supported now. We will consider adding this API as well. FYI,...

FREERTOS_WATCHPOINT_END_OF_STACK severely slow down the ISR response on C3 and C6 with debugger attached. (IDFGH-12539)

Hi @andylinpersonal! I have tried to reproduce it but still no luck. I am getting 1ms for both w and w/o FREERTOS_WATCHPOINT_END_OF_STACK + w and w/o the debug probe attached....

FREERTOS_WATCHPOINT_END_OF_STACK severely slow down the ISR response on C3 and C6 with debugger attached. (IDFGH-12539)

@andylinpersonal It seems I have reproduced this case. I slightly changed your example. This example works well when CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK=n or debug is not attached. The issue occurs when CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK=y and...

esp32s3, multiple signatures required for new firmwares (both at boot and during ota) (IDFGH-13711)

Hi @greenaddress! > esp32s3 supports up to 3 signatures blocks being setup during secureboot bootloader flashing however it seems that by default it only requires 1 at any given time...

> I would like to have any 2 valid keys out of the 3 digests, with one not being present or if present also needs to be valid (clearly it...

esp32s3, multiple signatures required for new firmwares (both at boot and during ota) (IDFGH-13711)

There are some disadvantages in your scheme: - Boot time will be increased. - In our scheme, [Applications should be signed with only one key at a time](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/security/secure-boot-v2.html#multiple-keys), to minimize...

LP Core crashes when enabling interrupts after a chip reset without power drop (IDFGH-15496)

Hi @ImproperCatGirl! > Modify the official LP core GPIO interrupt program Could you point out which [one of the examples](https://github.com/espressif/esp-idf/tree/v5.4.1/examples/system/ulp/lp_core)is tested? FYI, `lp_core_printf` does not support float and double prints....
