BM64 Bluetooth Radio Daughter Board v2.1 Flash Update "Connect Failed"
I have a AC320032-3 BM64 Bluetooth Radio Daughter Board. I am attempting to update the Flash from 1.1 to 2.1. When I try to connect through the UART and isupdate.exe application I get a "connect failed" message. I can successfully connect with the EEPROM_Tool.exe tool and download an .ipf file. This leads me to believe I am handling the MFB and STDBY/RST pins correctly (the red and blue LED's are continuously on). Other than the level on the EAN pin, is there anything different about getting the BM64 into Flash update (ROM Test) mode and EEPROM update (Flash Test) mode?
On a side note, the main purpose for updating to v2.1 is to use the analog audio output (a.k.a. internal codec). Unless I'm missing something this option isn't available on the 1.1 firmware. If I can get analog audio working with v1.1 that would allow me to continue debugging most of my project.
