RE: manual image installation with the hh.org bootldr - was Bootldr updater image - for easy one-step installation!!

Hi Ralf

That would be a possibility.
On the other hand the partitions must be the same as the bootloader.
The bootloader expects the Image starting at +512 kB from the beginning
of the flash. It then copies the Image to RAM (n.b. the whole image).
We only need the CE-Kernel and some DLLs in RAM, so there is code to fix
the bootloader limits by modifying the size entry of the image.
This messy thing makes it difficult to adapt the CE-image for bootldr.

Regards
Walter
