Hi,

I have download my software on a personnal BCM20736 board. And today I want to re-download a new vesion of this software but this message apper:

****Download failed - Press the reset button on the device and retry ****

With the VERSBOSE=1:

Downloading application...

I have try with the SDA to gnd, without. Or with the HCI UART Rx to gnd at the power up or after...

Always the same error...

The recover command failed and I have the same problem with other custom board

Do you have an idea to solve my problem?

Thanks

The application seemed to have been compiled properly including the cgs-to-hex conversion.

I did a download and compared my verbose log against yours and found that you are missing a portion where it should report "Detecting device...". I suspect that the uart ports were not detected/installed properly.

Can you plug in your board to the cable which you used for downloading, go to Device_Manager/Ports, and confirm that you see the two serial ports?

[Juar_2150386]

When I used the BCM20737TAG board I see the two serial port and I download my software properly but when I used my custom board I see one serial port and the failed error

I have no pull up to P1

SDA, SCL floating

All gpio non used (floating)

reset pull up with 10k

My old software run if I power up the board (without HCI uart)

And I can't dowload my new software on this board

[BoonT_56]

Some questions:

1) Are you using SIP module or SoC?

2) How do you download your app onto your board? Do you use the SDK or via a cable like FTDI USB-to-UART?

3) Can you post your download.log file in your build folder?

For recovery, can you use the following make target?

proximity-BCM920737TAG_Q32 recover UART=COMxx VERBOSE=1

I know you have tried to recover the chip by tying SDA to gnd and Vcc. But I just need to confirm that you carry out the below

steps and still you cannot recover. To recover:

1)Power off the device

2)Short SDA to GND

3)Connect the HCI UART

4)Power up the device

5)Wait 3 seconds and remove the short

6)Execute your recovery target build

HCI_Rx must be exerted upon powering up in order to enter Programming Mode

I use a 20736S and I download he software with a FTDI USB-UART

I have solved my problem, The Tx connexion between my UART and the custom board was corrupt (cut off)

The recovery procedure works and the programmation too

Sorry for the desagrement and thanks a lot for your time

Have a nice day
