Hello,
I am running u-boot 2018.11 at BeagleBoneBlack with the following setup.
I have EFI Grub image with tftp module enabled. This image is deployed by tftp and it is advertised by dhcp. When started Grub loads Linux kernel and initrd and boots OS.
Such setup works fine with qemu-arm and OVMF (TianoCore EFI).
Now, I am trying to use BeagleBoneBlack and do the following:
=> run findfdt => run loadfdt => print fdt_addr_r fdt_addr_r=0x88000000 => dhcp link up on port 0, speed 100, full duplex BOOTP broadcast 1 DHCP client bound to address 192.168.185.197 (20 ms) Using cpsw device TFTP from server 192.168.185.80; our IP address is 192.168.185.197 Filename '/bootarm.efi'. Load address: 0x82000000 Loading: ############################### 4.1 MiB/s done Bytes transferred = 448512 (6d800 hex) => bootefi 0x82000000 0x88000000
Then I see Grub menu for a moment and the console is constantly flooding be the following messages with very high rate (dozens of lines per second):
CACHE: Misaligned operation at range [9ce7e470, 9ce7e4b0]
At the same time I see in tcpdump that there is ongoing exchange between tftp server and the board. After some time I see that the kernel is booting and CACHE messages disappear:
bash-4.4# uname -a Linux 88cc78c5ecd6 5.0.0-rc1-default+ #1 SMP PREEMPT Tue Jan 15 19:23:17 MSK 2019 armv7l armv7l armv7l GNU/Linux
The question is how to fix this CACHE messages or their reason?
