Hello,
I am working with the BCM920736 board, and I want to enable OTA upgrade. For my application, the board will be embedded in a system with no USB access, so the only way to modify its code will be through bluetooth OTA upgrade. However, I cannot figure out how to activate it. I am following the guide included, but i am getting stuck on the "sign the SOTAFU Image" section. I cannot figure out how to do the step where I need to do:
C:\rsa\rel>WsRsaSign.exe rsa.pri ___.bin 3A19 1 1
I cannot find an rsa directory on my computer, so I cannot figure out how to run that exe. When i try to run it manually, I get an error.
Thank you,
--Jay Jackman

Please navigate the PDF produced by embeddedmasters at the following link: How to do OTA: Step by Step with PDF
If you still have questions let me know, but this document is generally sufficient for people to get OTA working.
