That's why I asked you earlier whether you want to be provided with such instructions ;-) I'm currently using the following u-boot patch for FEL booting u-boot, kernel and initramfs (with serial console on MicroSD breakout): diff --git a/include/configs/sunxi-common.h b/include/configs/sunxi-common.h index f7e87a2..e958bd0 100644 --- a/include/configs/sunxi-common.h +++ b/include/configs/sunxi-common.h @@ -330,6 +330,11 @@ CONSOLE_STDIN_SETTINGS \ CONSOLE_STDOUT_SETTINGS +#if defined(CONFIG_UART0_PORT_F) +#undef BOOTENV +#define BOOTENV "bootcmd=source ${scriptaddr}\0" +#endif + #define CONFIG_EXTRA_ENV_SETTINGS \ CONSOLE_ENV_SETTINGS \ MEM_LAYOUT_ENV_SETTINGS \ The 'boot.scr' file needs to be uploaded to the right location in RAM ('scriptaddr', which is currently 0x43100000) using the 'fel' tool too. And the DTB file needs to be patched to move UART0 pins to the SD card slot. This DTB patching can be done automatically in u-boot on the device (if u-boot is enhanced to implement this functionality), or on your PC before uploading it to RAM using the 'fel' tool. That's basically all. As you can see, not everything is perfect. But *if* there is some interest in this functionality, then I *might* be motivated to submit the necessary tweaks to the mainline u-boot for making the use of MicroSD breakout easier. I had a preliminary off-list discussion with Hans and Ian earlier, but they did not seem to be in favour of this idea. -- Best regards, Siarhei Siamashka -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
