I am developing my own source code for cc3200 OTA processing using AWS s3 bucket and pre-signed url .i was able to download the file "f43_sys_servicepack.ucf" and save in /sys/servicepack.ucf path but when i reboot the system still it boots up with old service pack. I am unable to find out what i am missing .Please if their any suggestion for updating service pack .

I opened file "/sys/servicepack.ucf" with flag value as 35 and also when i am closing the file i am sending the signature information also .

Before updating the /sys/servicepack.ucf file i have updated the file /sys/servicepack.sig

issue is fixed . it was the mistake from myside I was writing only few bytes into the "/sys/servicepack.ucf" file because of that i was getting error during file close .After writing all the bytes i was able to close the file successfully .
