AWR1642BOOST: Secondary bootloader parse FW image failed

Hi team,

SDK: mmwave_sdk_02_00_00_04

HW: AWR 1642BOOST ES2.0

Application: Secondary bootloader (CAN Downloader and Flash downloader)

We got attached document and secondary bootloader example code.

But we met a problem when we boot-up from flash by secondary bootloader.

After debug the code, we found the problem is on parsing BSS_SUBSYSTEM.

We tested the Secondary bootloader with SDK 1.0(01_02_00_05)/SDK2.0 fw image.

With SDK 1.0 FW, we can see the "Parsing completed".

With SDK 2.0 FW, we got halt-down.

The section length seems doesn't match between SDK 1.0 and SDK 2.0.

Do you have any idea that we can solve this issue on SDK 2.0?

SDK 2.0 xwr16xx_mmw_demo.bin

BSS_SUBSYSTEM(calculateImageOffset())

s_ImageParams.sectionPrms.secLen: 40/0  (readRPRCSecContent())

size: 40 (readRPRCSecContent())  <= The last debug message and got system halt.

SDK 1.0 (xwr16xx_mmw_demo.bin)
