Hi Rio,

For the BOOTMODE pin # mapping to DIP switches refer to this section (please ignore the example settings on the figure):

BOOTMODE pins select the following options (note the reversed order):

Please refer to the following TRM section for detailed description on how to select boot mode (primary and backup) and boot mode settings:

5.4.2 BOOTMODE Pin Mapping (Full Pincount)

Let me know if you have more questions.

Regards,

Stan

Hi Stan:

May you help to reply this way thus we can make it easy to follow?

SW2 / SW3 / SW4 setting (in Binary format) : 1100 0000 ......

BTW, the below is my notes for AM62X, I wish BU can offer this kind of format for all Boot modes.

Thanks.

No Boot (JTAG):
SW1: 11011111 SW2: 00000000

SD card boot:
SW1: 11000010 SW2: 01000000  The SW 1 is the right side DIP (See the yellow cirecled.), SW2 is the left side DIP.

Hi Rio,

For USB boot and SPI backup boot, the DIP switches should be set as follows:

SW4: SW2: SW3:

110 0101 0 0 001 1000

25M USB no-swap DFU Backup mode SPI

Hi Stan:

May you read this E2E?

AM62L: USB MSC Boot - Processors forum - Processors - TI E2E support forums

Have you verify and check if this is really working well?

Hi Rio,

As far as I know USB stick boot is supported in ROM code. There is only a limitation which is described in errata document is that ROM doesn't support files larger than 2MB.

Not sure how it is supported in secondary boot loaders. I can see it is currently not supported in Linux SDK 11.02:

2.2. Software Build Sheet — Linux SDK for AM62L Documentation

Hi Stan:

For the USB Mass Storage boot, please help the TI RD to implement this can document for how-do in detail, thanks.

Reason: DS shows the USB boot is supported.

Hi Rio and Anastas,

I have a little more info today. Due to a bug in the ROM code itself, first stage boot wasn't possible. That's why MSC boot wasn't implemented in u-boot and Linux. The bug has been fixed in ROM in silicon revision 1.1, hence now MSC boot is back in the queue for u-boot and Linux. Linux SDK documentation and how-to-s will be updated accordingly once SDK gets updated.

Regards,

Stan
