Hi!
I have beaglebone-ai. I would like to use dfu. I build u-boot (is working from sd card). But when I download u-boot-spl.bin using usbboot-stand-alone from dfu-util doesn’t detect the board as dfu target.
Thanks.
Hi @imikec what branch or tag of u-boot are you currently using to try dfu? I know TI directly supported this configuration in their ti-u-boot tree, but us at BeagleBoard.org never really touched dfu…
Regards,
Here is the tag: U-Boot 2023.07-rc1-00210-g8774e45e89. The problem is that there is no default config for non-secure chips. I am using older bbb-ai board revision. Could that be an issue?
Okay, you are using a random git commit from u-boot, for production you really should stick with a released tag, unless your doing development…
I’d use: Release v2023.07.02 · u-boot/u-boot · GitHub over 2023.07-rc1-00210-g8774e45e89

Regards,
Tried your suggestions, but SPL doesn’t start. Is there a way to enable uart debugging or to blink LED, to see where SPL is dying? On BBBAI ttyS0 is used as debug port.
CONFIG_SPL_TEXT_BASE=0x40306D50 is not a correct value. It should be CONFIG_SPL_TEXT_BASE=0x40300000 since we are talking about GP cpu not a HS one.
