From d93dce11f39aaf5c2b246e68f20d47b92e99d331 Mon Sep 17 00:00:00 2001 From: Biwen Li Date: Fri, 24 Jul 2026 14:17:58 +0800 Subject: [PATCH] arm64: dts: imx8ulp-evk: Update rpmsg resource table address The MCU firmware copies the rsc table to a fixed address (0x1FFF8000) at startup. However, this address is occupied by variables used in the MCU firmware, so copying the rsc table there corrupts those variables. Move the rsc-table reserved memory region from 0x1FFF8000 to 0x20000000 to avoid the conflict. The M33 firmware linker script has been updated accordingly to place the rpmsg resource table at 0x20000000 (DTCM m_rsc_tbl region).
