Subject: [PATCH] configs: am65x_evm: Define the maximum file size for DFU
Date: Tue, 24 Nov 2020 15:59:34 +0530	[thread overview]
Message-ID: <20201124102934.3319-1-a-govindraju@ti.com> (raw)

In include/dfu.h, if CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then it is
defined as CONFIG_SYS_DFU_DATA_BUF_SIZE. This is 128 KiB for a53 core and
20 KiB for r5 core. If a larger file is transferred using dfu then it
fails.

CONFIG_SYS_DFU_DATA_BUF_SIZE can not be increased as there is not enough
heap memory to be allocated for the buffer in case of R5 spl.

Fix this by defining CONFIG_SYS_DFU_MAX_FILE_SIZE as the default
CONFIG_SYS_DFU_DATA_BUF_SIZE value.
