From f2c644e0b8bc7dc842c8b27e65c69e503687296f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Fri, 24 Sep 2021 23:06:59 +0200 Subject: [PATCH] tools: kwboot: Patch destination address to DDR area for SPI image MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit SPI/NOR kwbimage may have destination address set to 0xFFFFFFFF, which means that the image is not downloaded to DDR but rather it is executed directly from SPI/NOR. In this case execution address is set to SPI/NOR area. When patching image to UART type, change destination and execution addresses from SPI/NOR XIP area to DDR area 0x00800000 (which is default for A38x).
