I don't have a Sterling EWB with me but I tested with a CY equivalent EVK and don't really hit this issue. Attached is my serial terminal log.
Can you confirm that this issue is only seen when you are trying to upgrade to snip.uart? also I am hoping that you are not trying to boot with the factory reset app which turns out to be ota_fr (I know its stupid to ask but just to get all the bases clarified)...
ota_fr.txt.zip 1.2 K
Hey, thank you for your response. (Also, feel free to ask any stupid questions!)
I don't believe there is a factory reset happening, only a software reset caused by the ota_fr app itself.
I also just tried downloading the snip.scan example project instead of the snip.uart project, and I ran into the same problem. The ota_fr app still loads up after the reset, but I expect the snip.scan app to load up.
I am confused on the OTA process of upgrading the application. Does it first store the binary data in external flash and then copy that to internal flash? If so, why would the bootloader fail to recognize the new flash memory?
the OTA example code would not success result on Laird EWB
would you help me to check about Laird bootloader implement?
