AM62L: USB DFU and MSC boot

Tony Tang
Mastermind 28922 points
Part Number: AM62L

Tool/software:

From the build sheet, no support for USB Host and device boot. It is needed. Especially for customers who worked on AM62x using DFU for eMMC flash on production line.

https://software-dl.ti.com/processor-sdk-linux/esd/AM62LX/11_00_05_02/exports/docs/devices/AM62LX/AM62LX_build_sheet_11_00_05_02_files/AM62LX_build_sheet_11.00.05.htm

From errata, there is some problem on DFU boot, but not say it can't be supported definitely.

#1. What is the conclusion if support DFU or not on this device?

#2. If yes, can do DFU boot on AM62L EVM in HW design? I tried to connect J19 to PC, can't detect USB device with below boot mode setting: 

#3. Is there a short plan to support DFU in SDK?

    Hi Tony,
    Have we tried configuring USB-DFU as primary boot mode on your setup?

    Hi Hong,

    follow the boot mode setting in academy https://dev.ti.com/tirex/explore/node?node=A__Aeit-XcsDs051LW6Ji4kOg__AM62L-ACADEMY__6F61DO6__LATEST

    Can boot to below, seems should rebuild with patch/configuration for DFU.

    Hi Tony,
    I'm attaching two logs from USB-DFU booting with Linux SDK 11.0.5.2, one is on host side, one is on target side, where BOOTMODE[15:0]=0053.
    Best,

    Seem my original console log is right, should go next step to download tispl.bin, forget tried or not. anyway, now it works, no need to rebuild with extra configuration.
