|
|
|
+ If no softreset save registers are found on the hardware
|
|
|
+ "bootcount" is stored in the environment. To prevent a
|
|
|
+ saveenv on all reboots, the environment variable
|
|
|
+ "upgrade_available" is used. If "upgrade_available" is
|
|
|
+ 0, "bootcount" is always 0, if "upgrade_available" is
|
|
|
+ 1 "bootcount" is incremented in the environment.
|
|
|
+ So the Userspace Application must set the "upgrade_available"
|
|
|
+ and "bootcount" variable to 0, if a boot was successfully.
