help
|

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.
