15:39 <f_> I highly think some of bl21 is used for ddr init.

16:21 <f_> But now that I looked at my DMC init and PLL init code let's look at PCTL init

16:22 <f_> Will take a long time.

16:46 <jdp_> Does anyone have experience building and running an image for LibreComputer LePotato (S905X)? I have successfully built an image using "MACHINE=libretech-cc-sdboot bitbake amlogic-image-headless-sd", and then flashed onto an SD card, but my board does not seem to boot. I have successfully booted the board with Raspbian in the past using the same hardware so I don't believe hardware is the issue but I am open to being wrong.

16:46 <jdp_> Any help or direction would be greatly appreciated!

16:47 <f_> Do you have UART logs?

16:49 <jdp_> I do not. My apologies I am new to using this hardware, would these be obtained through the top-left USB port using a male-to-male connector?

16:49 <f_> Don't worry :)

16:50 <f_> Have a look at the GPIO pinout and wire your USB-to-TTL device accordinately (DON'T CONNECT 3V3/5V)

16:52 <f_> namely GPIO 14 and 15 IIRC

16:52 <f_> Maybe also connect Ground

16:52 <f_> Oh wait.. jdp_: Do you have a USB-to-TTL UART adapter?

16:56 <jdp_> I do not, but I can find one and come back

16:56 <f_> These are very cheap

16:56 <jdp_> unless there is another way of going about this?

16:57 <f_> Not that I'm aware of.

17:02 <f_> Oh wait.

17:02 <f_> jdp_: https://hub.libre.computer/t/troubleshooting-boot-issues-on-libre-computer-aml-s905x-cc/46 did you try this?

17:03 <f_> Which LEDs lit up?

17:10 <jdp_> the blue and red leds were on solid

17:11 <f_> Oh so U-Boot doesn't boot.

17:11 <jdp_> just to be clear, I am trying to boot off of an SD card, and I do not have an external eMMC connected

17:11 <f_> Your SD card isn't flashed correctly.

17:13 <jdp_> I flashed using both etcher and raspberry pi imager, and I flashed "amlogic-image-headless-sd-libretech-cc-sdboot.wic" onto a sandisk extreme 64GB card

17:14 <f_> Don't use Etcher.

17:14 <lvrp16> wic files are not written via raspberry pi imager
