SmartBond™ DA14682 and DA14683

Single-chip high-security Bluetooth 5 solution with expandable memory

da14682-3.svg

The SmartBond DA14682 and DA14683 are the world’s first single-chip solutions for Smart Home, Industrial and wearable devices that meets the highest security standards. These highly integrated System-on-Chip (SoC) devices support Bluetooth 5 as well as Bluetooth mesh, and include a range of dedicated features to ensure cutting-edge security for both consumers and developers.

As part of our SmartBond range, both SoCs offer industry-leading performance from the lowest power consumption and smallest footprint. Their flexible architecture ensures plenty of processing capacity when you need it while saving power when you don’t. It also allows the devices to manage multi-sensor arrays and enables always-on sensing.

Both devices offer extensive memory capacity and differ only in their memory configuration. Specifically, the DA14683 supports unlimited external Flash for maximum design flexibility while the DA14682 includes 8 Mbits of onboard Flash, making it ideal for applications with tight space constraints. Both options allow you to benefit from over-the-air updates.

To further simplify your development, our SmartSnippets™ software and versatile Hardware Development Kits help you optimize your software for power consumption.

DA14683BB printed 4 times on reset

Posted by newmanp1 30 points 9 replies
0 upvotes

I am using a modified version of the BLE Peripheral sample on hte DA14683 USB Devkit.

I am trying to use the UART connected to the JLink at 115200bps for printf

Everything is working but when the system is reset it prints out the following over the UART at 57600bps

DA14683BB

DA14683BB

DA14683BB

DA14683BB

This causes issues because it prints out garbage at startup due to mismatched baudrates.

I can't find where in the SDK this print is.  Is there a way to disable it?

Hi newmanp1,

Thanks for your question online. The ‘DA14683BB’ is printed by the bootloader. Did you program the QSPI flash and after resetting the DK you can see the ‘DA14683BB’ ?

Thanks, PM_Dialog

Hi,

Yes that is what I am doing.

Is there anyway to turn it off?

Hi There,

This is the Bootloader, so you cannot disable it. However, if the QSPI flash is programmed, you should not see that on the UART. Does the device boot as expect it? Can you detect it over the air?

Thanks, PM_Dialog

Yes the QSPI is flashed and everything is working as expected. When I make changes they are reflected so I know the flashing is working properly.

After reading this doc it sounds like I need to set the boot flags in the OTP to boot from QSPI.

https://www.dialog-semiconductor.com/sites/default/files/an-b-046_da146…

It isn't very clear on how to do that. Can you please provide the procedure on how to do this?

Thanks for the help!

Hi There,

Why do you need to program the OTP? Please keep in mind that OTP stands for One Time Programmable, so you are not able to program it or erase it multiple times.

I would recommend to erase the QSPI flash and then program it again with you FW.

What is the UART baud rate that you are using?

Thanks, PM_Dialog

newmanp1 30 points

The App Note I linked previously states  hat the OTP header address "0x7F8E9D0-0x7F8E9D7" controls whether it takes the "Serial" or "NVM" boot path. I understand what OTP means which is why I asked for clarification prior to writing any values.

I want to run my application from the QSPI and use both UARTs at 115200.

PM_Dialog

Hi There,

As mentioned in my previous reply, the sequence that you can see in the terminal is generated by the bootloader and indicates the chips version. You should not burn the OTP in order to boot from QSPI Flash.

All you need to do, is to compile any of the SDK examples and use the python scripts from the SmartSnippets Studio to program the QSPI Flash.

Which SDK example are you trying to run?

Thanks, PM_Dialog

Not sure if this is directly relevant but I am using the "DA14683 Development Kit USB".

I also see the multiple "DA14683BB" messages at power on.  They only show up on the CDC port that enumerates as "JLink CDC UART Port (COMx)".

I have been working with the system for a while now, with many successful erase and program cycles of the QSPI.

I'm not sure what the primary purpose of that JLink CDC port is, but I have never seen that port to do anything other than display those "DA14683BB" messages, and I have left a terminal hooked up to it most sessions. If I wanted to see printf() I redirected to UART2, which I have hooked up to an external UART->USB adapter board.
