CC3220SF-LAUNCHXL: Problems with CC3220SF update from DropBox

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: CC3220SF, CC3235SF

Hello!

I use CC3220SF and my program based on cloud ota example. CCS version is 10.4.0, SDK version is 5.20. I use DropBox as cloud.

I changed defines in otauser.h and added this certificates to userFiles in my CCS project.

#define OTA_SERVER_ROOT_CA_CERT                     "digcert_high_assurance_ca.der"

#define OTA_CONTENT_SERVER_ROOT_CA_CERT  "digcert_global_root_ca.der"

But update still doesn't work.
