Hi All,
I work with DA14531 Development Kit-USB. I use the Keil Development Tool and SmartSnippets Toolbox.
I can't download an image file to the flash. I try to use Booter, SPI Flash Programmer, and EEPROM Programmer. I always get the same result:
[INFO General @20-07-19 20:23:04] Could not measure total IR len. TDO is constant high.

[ERROR SPI Flash @20-07-19 20:23:04] Failed downloading firmware file to the board.
In Keil, I got this: "No Cortex-m SW Device found".
Before according to this problem I download the Firmware in SPI flash which set the device in deep sleep mode immediately after system initialization. I saw that the downloaded firmware works. The device wakes up from sleep mode every 10 seconds and goes to sleep again.
My question is what can be the reason for image downloading failure and how can I fix this problem?
Thanks.
Hi,
I have recently started to work with the DA14531 Kit-USB.
After reception of the board I have tested the Demo. Everything was fine: led was blinking and the BD address was received by my computer terminal via UART.
I then tried to use the blinky example, as explained in the tutorial, and here comes the problem:
When I start the debug session in Keil, I can see the led blinking (I have tried to change the blinking frequency to be sure that it was the good code, and it is), but I can't receive the communication with my terminal. Am I missing something (like hardware configuration, pin assignments or something)?
Do you have any hint to solve this?
Thank you in advance.
