I am using the RELOCATE_FROM_FLASH feature. When this is defined, the code is "set" to 0x00100000 and burned into flash at that address. My question is do I go about changing this? I have the flash memory map figured out as: BOLO 0x00000000 LOLO 0x00040000 Start of rest 0x00080000 There is a 1/2 meg hole here if the code is burned into flash at 0x00100000. Is there anyway to change this? Thanks Joe

jjfitzy, The settings that you're looking for are done within the file WINCE420\Platform\xxx\files\config.bib. Look in the Platform Builder help and it will explain to you the format of a bib file. Please be aware that there is the potential for wiping out your bootloader and other parts of flash in doing this. I would also recommend checking out a previous thread related to the config.bib. http://www.logicpd.com/su.../viewtopic.php?t=279 Regards,

Hi Aaron, Thanks for your reply. I am familiar with config.bib and also lha400_10_config.bib. If you would point me to the correct item to change it would be most helpful. Thanks, Joe

jjfitzy, I spoke a bit hasty and refered you to the wrong config file. You don't want to touch config.bib. Instead please look inside \WINCE420\PLATFORM\LoCE\inc\card_engine\xxx_config_bib.h and make changes there, the settings should be easy to modify. Regards,

Aaron, Again, I am familiar with lha400_10_config_bib.h file. I do not see the place in it to change the FLASH load location for the RELOCATE_FROM_FLASH option. Would you please supply either a specific entry to change or an example. Thanks, Joe

Please read the comments pertaining to "XXX_BUILD_IMAGE_START" and "XXX_BUILD_ROMOFFSET." Basically, XXX_BUILD_IMAGE_START corresponds to the virtual address of the nk XIP region. This gets added to XXX_BUILD_ROMOFFSET to calculate the physical address of the beginning of the image. Note, the calculation is done in a 32-bit accumulator, so ignore any overflow.
