Is there any limitation on how to boot the processor from an SD card? I've tried to format my SD card using the official SD Card Formatteer from the SD association, using different cluster sizes on my 8 GB Kingston uSD card, and so far my tests tell me the processor doesn't seem to boot for any cluster size higher than 4 KB. (I get the 'CCCCC' string on my terminal).
I've tried with the tool recommended on the Wiki (HP format tool) and it works ok, but I can't change the cluster size to anything higher than 4096 KB with this tool, and this limits the writing and reading speed of my application as I can only read or write eight sectors each MultiBlocks command.
I'm using a BeagleBone Black Rev C development board. I'm using the bootloader provided by Texas Instruments, with a slight modification to the assembler code to enable the NEON and VFP.
Any ideas, help or workaround on this is appreciated.
