To: u-boot
Hi,
I am facing intermittend boot failures resulting in a data abort. Boot log
and environment attached below. The uboot is built with rpi_defconfig with
OF_BOARD to get uboot to pass through the FDT.
Note:
(1) If I boot this image directly using the RPI bootloader, the kernel
(with initramfs embedded) boots fine consistently.
(2) However, I get inconsistent failures with uboot. My gut tells me
memory is getting corrupted.
(3) Sometimes just adding one option to the bootargs breaks the next boot.
(4) It seems the FDT address changes slightly (see failed vs OK). Not sure
if this is expected from start.elf (I assume the FDT address is supplied to
u-boot).
(5) Is the size of the image overwriting anything in u-boot? I am not that
familiar with the u-boot memory map.
I boot using the following environment changes:
bootargs=bootslot=a console=ttyAMA0,115200 root=/dev/null
bootcmd=fatload mmc 0:1 ${kernel_addr_r} kernel.a.img ; bootz
${kernel_addr_r} - ${fdtcontroladdr}
Any ideas?
Regards,
Fred

I found a patch proposal where someone suggested that ${fdtcontroladdr} and
${fdt_addr} could end up being saved in the environment (saveenv), and
causing a old value getting loaded.
This resulted me in doing two things, which fixed the issue:
(1) Remove both these environment variables (env delete) before saving
(2) Using ${fdt_addr} for bootz
Everything now works perfectly.
Would you mind clarifying the difference between ${fdtcontroladdr} and
${fdt_addr}? I got the impression I had to use ${fdtcontroladdr} with
CONFIG_OF_BOARD, but that could have been a faulty source of information.
