commit 129e9d30055e5cbed5ad6f0229772a3dc89fa529
Author: R. Diez <rdi...@rd...>
Date: Mon Feb 2 18:00:49 2026 +0100
configure.ac: Replace --enable-malloc-logging with a new runtime log level.
About why the new log level LOG_LVL_DEBUG_USB has the same value a
LOG_LVL_DEBUG_MALLOC, see the mailing list discussion starting here:
Replacing --enable-verbose-usb-comms in configure.ac
https://sourceforge.net/p/openocd/mailman/message/59215751/
Other minor fixes included here which are probably
not worth submmitting in separate patches:
- In error message "level must be between -3 and 4", increase 4 to 5.
- LOG_DEBUG_IO was passing LOG_LVL_DEBUG instead of LOG_LVL_DEBUG_IO.
