Hi Sascha,
I read your answer again and realized my misunderstanding.
So essentially what you say is that all 48 bits of the address space would be
set as flat 1:1 un-cached and only the SRAM region will be set as cached.
In that case the UART at address 0xD0_0030_7000 and our ROM at address

The stickypage is a hack to have a 4K hostfile persist over reboot. This
was so far done by compiling the stickypage separately and referencing
it from the device tree via the magic $build variable that expands to
the working directory.
This breaks a number of assumptions:
- KBUILD_IMAGE:
multi_v8_defconfig builds images for Virt, ZynqMP, Rockchip and i.MX.
Convention is for unadorned Labgrid environment file to be a symlink to
a file with a more telling name.

But the UART is set on a total different memory space.
The SRAM where barebox runs and also given as membase and memsize is in the
region of 0xC0__
The UART is in the region of 0xD0_0030_7000.
According the tarmac log, it looks like access to this location caused the

Hi Sascha,
I think I found an issue with the CONFIG_MMU feature.
When the code under barebox_pbl_start calls mmu_early_enable, the MMU is set
such that only the given SRAM is defined (membase, memsize).
But then, if DEBUG_LL is in use and the function pr_debug is called we get an
exception
