Hi Vikas,
Try to remove this magic (press 'c' on the keyboard when at the boot
time), I'd suggest to add a follow-up patch to move all the selected SPL
related configuration from "arch/arm/mach-stm32/Kconfig" under STM32F7
to default configuration file (stm32f746-disco_defconfig). Then if the
people want just boot up u-boot itself, what they need to do is just run
"make menuconfig" and then de-select "Activate Falcon Mode"
(SPL_OS_BOOT). Then everything will be fine.
Thanks.
Best Regards,
Bo Shen

This commit supports booting from stm32 internal nor flash. spl U-Boot
initializes the sdram memory, copies next image (e.g. standard U-Boot)
to sdram & then jumps to entry point.
Here are the flash memory addresses for U-Boot-spl & standard U-Boot:
- spl U-Boot : 0x0800_0000
- standard U-Boot : 0x0800_8000
Is there another patchset missing on mainline for booting via spl?
No, you just need to flash spl & next image at above mentioned addresses. By
default spl expects kernel image.
To boot u-boot, press keyboard character 'c'.
you might need to keep on pressing 'c' it for some time as the keyboard entry
acceptance & detection window is very small.

I'm using openocd to program
openocd -f board/stm32f7discovery.cfg \
-c "init" \
-c "reset init" \
-c "flash probe 0" \
-c "flash write_image erase ./spl/u-boot-spl.bin 0x08000000" \
-c "flash write_image erase ./u-boot.img 0x08008000" \
it should be u-boot-dtb.bin.
Bingo!
Thanks Vikas!!
