Thanks in advance. We are finally getting a chance to migrate to the mmu branch. Our goal is to use the TSE and Marvell. We've seen in the wiki that we will need to do some adds to the *.dts...

You have to set the "Memory base address" to the address of your main RAM, not including the MMU kernel area offset (0xC0000000). For example, I have 0x04000000 for DDR.

For the simple case -- you should uncheck "DTB at physical address" and instead check "Compile and link device tree into kernel image" and put the path to your DTS file there.

The fancier alternative, which I haven't tried --

IF you are:

  • building your device tree into your FPGA image (onchip ROM)

  • OR loading it through u-boot

  • OR storing it in flash

you need to compile your DTS (source) to a DTB (binary) manually (I don't know the tool/command) and use the latter. Uncheck "Compile and link device tree into kernel image". Check "DTB at physical address" and put in the address of the onchip ROM or flash or wherever u-boot puts the DTB in RAM.

If this clarifies it for you, please add the missing information to the wiki pages you used.
