I'm using a Lindenis v536 SBC. I've built an image, loaded it on an SD card, and now I can observe these messages over a UART interface:

This is called the SPL, right? This starts at the 8k address on the SD card. I'm guessing it can't find Boot1 at the location it expects on the SD card. However, I can't seem to find this code in the U-boot sources. When I look through the sources in the Lindenis GitHub repo I only find these strings in binary files. Is this something that Allwinner compiled and only released as a binary? Any pointers of where I could look next to troubleshoot this? -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
