@mantriyogesh PTAL. Thank you.

Pull request overview

This PR fixes const qualifier violations in the esp_hosted component to comply with stricter compiler flags (-Wwrite-strings and -Werror=discarded-qualifiers) enabled in ESP-IDF CI builds. The changes add const qualifiers to string pointers that are assigned string literals, preventing implicit discarding of const qualifiers.

Changes:

• Updated component version from 2.10.0 to 2.10.1
• Added const qualifiers to string pointers in serial_if.c (3 locations across 3 functions)
• Added const qualifier to static string pointer in mempool.c

Thank you @sudeep-mohanty ,

I will push your commit tomorrow, as blocked on 2.11.0. Will then need to pus hthis as 2.11.1

Do you have the pre commit hook or something to verify this?

[sudeep-mohanty]

2.11.1 sounds good to me. All apps in IDF already reference esp_hosted version >= 2 in the idf_component.yml. Do let me know if you need me to update this PR with the correct version.
