From 6ad84408b50b2849d4c871ac33cb827bb8e76c96 Mon Sep 17 00:00:00 2001 From: dannyray019 Date: Wed, 27 Aug 2025 10:46:49 +0800 Subject: [PATCH] bsp:k230:add pdma support for uart driver Added pdma support for uart driver and a test file test_uart.c. The test uses pdma to improve uart send speed, to check if the driver works correctly.
