Trying to setup an UBL for a cc2540 using BLE1.2.1. Any success stories?
I tried HostTestRelease on CC2540USB-UBL
- without modification the USB doesn't seem to load.
- tried to add a hard reset force bootloader value to 1, doesn't trigger the MSD.
*******
I also tried to follow the USB-MSD pdf guide with the Keyfob project
By adding the ubl_app.c and the preprocessor definitions and using the cc254x_f256_ubl_msd.xcl. The Keyfob project that was once working no longer advertises.
Plugging in the USB also doesn't trigger USB-MSD when I tried (1, non-zero hardreset counter, 2 calling ublAppForceBoot() early)
Also tried to include CC2540USB files to the project targets and removing CC2540EB. Doesn't help.
Any pointers?
Best Regards,Sam
Answering my own question:
Giving credit to my colleague, he told me I forgot to install the ubl hex file in. I thought the binary given was a sample binary. But it was actually the bootloader itself...
