Dear Marek Vasut,
In message 201205301309.23163.marex@denx.de you wrote:
Why would you need to initialize DDR though the JTAG debugger?
The system has some BootROM, which does the DDR init. But without special header in the NAND, the DDR won't be inited ... that was my point about initing it via the debugger.
That's actually a different topic - how to install a U-Bootimage to NAND. The question here was how to debug U-Boot, so it seems a valid assumption that there is actually some code to debug. And in this case the JTAG debugger is supposed not to mess with the initialization, but leave the system alone so it run the same code you actually want to debug.
Best regards,
Wolfgang Denk
