When enabling HAVE_REDUND in uboot-tools, will it work if i have the redundant
partition in the same sector

I'm using spare bytes of the nvram of the RTC chip to determine which of my two
kernels should be booted. Trying to scrip that in u-boot script I'm doing the
following.
1. Load 200010 with 0 (mw.b 200010 0)
2. Load 200014 with value from nvram (i2c read 68 15 1 200014)
3. if cmp.b 200010 200014 1
in i get "Yes"
Thanks

Thanks

Here is a scenario, i have a working version of the u-boot on my board, and am
trying my changes. Am not sure it is going to freeze the board, so would like
the present version to load the new version for testing before it can be burned
to flash. Is it possible to do this or is it already done
Sorry! my mistake, the code is in main.c

bootcount_store(bootcount);
sprintf (bcs_set, "%lu", bootcount);
setenv("bootcount", bcs_set);
