[LinuxBIOS] Question of making 1MB flash rom?

[Hao Li]

Hi all,

When I make a 512KB image which contains a payload with about 300KB size, it
will okay to jump to payload to execute

the payload. But when I make a 1MB image contains the same payload as 512KB
image has, it cannot jump to

payload to execute. It reports that checksum is not okay. Is there some
restriction elfboot() has??

Does anyone meet this problem before?

Thanks

Sorry for the late reply.

This is probably because the chipset does not decode 1Mb to the flash
chip, but only 512kb. Which board is it? Look into the southbridge
code.
