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:
(信息一般@20-07-19 20:23:04)不可能的措施e 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 Margo Safaryan,
Thanks for posting online! Please check out the arch_set_deep_sleep() API - when the systems enters the deep sleep mode, the debugger is disabled. I suspect that you are trying to use the debug when it is disabled by the firmware.
Could you please set the DIP-switch properly in order to de-attach the flash and then try to program the board via Keil IDE? Additionally, you can try to program it through UART.
Another possible solution might be to reset the board, then it will not be in deep sleep mode for 10 sec, and then quickly try to connect over JTAG.
Thanks, PM_Dialog
Thanks for your quick reply. I change the DIP Switch configuration for using UART and it works ))))
Hi Margo Safaryan,
Glad that you got it working and thanks for the indication. If you have any other issue with the DA14531, please raise a new forum thread.
Thanks, PM_Dialog
Hi PM_Dialog,
I will raise a new forum thread if it will be needed. Thanks for support ))

Hi PM_Dialog,
I have one more question according to this subject.
I have the same problem. I can't download an image file to the flash.
I downloaded some Bluetooth software in OTP memory instead of the secondary_bootloader.
I change the OTP header and put "Application Programmed Flag #1 -Yes" and "Application Programmed Flag #2 -Yes". Now the software downloaded in OTP memory is always running.
After all this, I have a problem with image downloading. I get errors in both cases UART and JTAG.
In JTAG case:
[INFO General @20-07-27 19:27:54] Could not measure total IR len. TDO is constant high.
[ERROR General @20-07-27 19:27:54] No known chip found while opening JLink connection. Terminating proccess...
[ERROR OTP Header @20-07-27 19:27:54] Failed downloading firmware file to the board.
在UART的例子:

[INFO OTP Header @20-07-27 19:30:59] Started download procedure...

[INFO OTP Header @20-07-27 19:31:07] Please try again. If problem persists refer to User Manual AN-B-072 (//www.wsdof.com/an-072-booting-from-serial-interface) and check jumper settings. For booting from 2-wire UART (P0_0 and P0_1) see Figure 10. For booting from 1-wire UART P0_5 see Figure 6.

How can I fix the firmware file downloading problem?
Thanks, Margo Safaryan
Hi Margo,
So, if I understood correctly, the OTP is programmed, and you cannot burnt the SPI flash? Could you please try to explain better the steps you have done, so that I can understand the root cause of this issue?
Thanks, PM_Dialog
Hi PM_Dialog,
Yes the OTP is programmed, and I cannot burn the SPI flash and SysRAM. In Keil, I got this: "No Cortex-m SW Device found".
I burn the OTP. I change the OTP header, put "Application Programmed Flag #1 -Yes" and "Application Programmed Flag #2 -Yes" and burn it too. After all this, I have a problem with image downloading. I started to get the mentioned errors.
Thanks, Margo Safaryan
Hi Margo Safaryan,
Apologies for the delay. Are you trying to connect via JTAG or UART through the SmartSnippets Toolbox? Since you cannot program the Sys-RAM thought Keil, I would recommend first checking if the tool can detect the JTAG SN number (from the options for target window), Additionally, did you disable the JTAG from the OTP Header?
Thanks, PM_Dialog
Hi PM_Dialog,
I tried to connect via JTAG and UART, the connection fail in both cases.
In Keil JTAG SN number detected but I got "No Cortex-m SW Device found" error when tried to debug.
I didn't disable JTAG from the OTP Header.
Thanks, Margo Safaryan
Hi Margo,
一次啊TP is programmed and the Application flags (1&2) set the booter by passes the ROM boot sequence that checks SPI/UART etc for applicaion images.
