SK-AM62P-LP: About Boot time optimizations, configurations in syscfg are different

Part Number: SK-AM62P-LP
Other Parts Discussed in Thread: AM62P,

Tool/software:

MPU: AM62P

SDK: 10.0

EVK: SK-AM62P-LP

URL: https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/10_00_07_04/exports/docs/linux/How_to_Guides/Target/How_to_boot_quickly.html

Description:

Chap. 4.1.10.2.1, we try to enable DMA in the bootloader, and find out that configurations of BOOTLOADER shown on the URL differ from what we have. (See below comparison charts). 

Yours on left hand side is published on URL; ours on right hand side is from "make syscfg".

You have 3 bootloader configs: CONFIG_BOOTLOADER_FLASH_MCU, CONFIG_BOOTLOADER_FLASH_LINUX and CONFIG_BOOTLOADER_FLASH_HSM.

We have 1 bootloader config: CONFIG_BOOTLOADER_APP

Question:

I think we should have identical syscfc for quick boot solution. If so, how can we get your configurations for reference? If not, what bootloader config should be?

Thank you.

    Hi, all,

    Realized that the illustrate is from sbl_ospi_linux_stage2. We now use sbl_sd_linux, regarding boot time optimizations, should we keep it as-is? or align with sbl_ospi_linux_multistage in FALCON mode? Or recommend to run sbl_ospi_multistage instead? Thanks.

    BRs
