Dear Joakim Tjernlund,
In message OF18CA6215.DC3A539B-ONC12577D1.00439A8B-C12577D1.0043BB01@transmode.se you wrote:
What exactly is a "soft reset" in U-Boot? And how would you perform one?
Not in u-boot, but Linux or a privileged linux app. could.
Could do what? Modify the memory map such that the Flash is mapped as it was (eventually) when U-Boot is running, and then jump right in the middle of nowhere?
That would be invoking undefined behaviour in it's purest form.
Anything can happen then.
Best regards,
Wolfgang Denk
