Hi,
my connection is unstable using JTAG with my custom board.
first I can detect my board, but when i go into the toolbox, and download the booter firmware, it goes wrong.

what's the problem? my cable or my board?
Hi daniel59,
这是一个从Jlink软件和指示not from Smart Snippets (when connected via JTAG, Smart Snippets uses the jlink in order to access the device). You mentioned that you have a custom board, so do you have the JTAG on you custom PCB or you are using either Pro or Basic DK in order to program your board? I highly recommend you to check if you have configured correctly the SPI Flash pins in the Board Setup tab of SmartSnippets toolbox. Probably there is no connection between the processor on the custom PCB and the Jlink fw that tries to communicate with the device. That could be anything from connections up to problems with the PCB that make the 580 unable to operate. My suggestion is to check if the bootloader is executing in order to verify that the 580 is operating correctly. You could probe the P04 and P05 pins, and that pins should be toggled executing part of the bootloader, so when connecting to a terminal you should see the device printing garbage. Also i would suggest you to connect the board using the Jlink itself, instead using Smart Snippets and also i would try to download code via Keil.
Thanks, PM_Dialog
Hi PM_Dialog,
I think I'm using a custom JTAG device, connected to my custom board.
I can use Keil go into the debug session, but when i run the code,using ble_app_barebone project, it go to code:
if ((GetWord16(SYS_STAT_REG) & DBG_IS_UP) == DBG_IS_UP)
__asm("BKPT #0\n");
I tested my 5 boards only 1 board can go through the code.
Is my boards quality bad?
Hi daniel59,
Could you please clarify what you mean with custom JTAG device? Which version of J-Link are you using? This means that you get an NMI. Could you please try to debug your code and try to find the cause of the NMI? Where does your application code get stuck? If unaware of how you can find the reason of the NMI, I would suggest you to have a look atTutorial 8: Debugging methods_v1.1from our support portal. Also, it is very possible that is error is due to bad quality of you PCB.
Thanks, PM_Dialog
Hi, PM_Dialog
Er...I mean custom J-link device. Which is like J-Link EDU Mini but only have swdio, swclk, vcc and gnd.
我正在使用jlink v5.12f，由smartsnippets studio v2.0.6推荐用于DA14580。
I look the tutorial 8, but I cant found where the error is using both 2 methods.
I‘m thinking about my power supply. Commonly use J-link is directly connect swdio to pin 25, swclk to pin 26, vcc to pin 15 and gnd to pin 16, using QFN40 DA14580 .
but for my board, because i want to both charge battery and JTAG, I connect swdio to pin 25, swclk to pin 26, gnd to pin 16 but vcc to a battery management chip ltc4054 to charge li-ion battery, then connect battery to a 3.3v LDO, then connect 3.3v output from LDO to pin 15.
这会让事情错了吗？
i tried many times, sometime toolbox can find chip but shows CPU could not be halted, sometime toolbox cant find chip, sometime it directly shows Failed writing file D:\Desktop\empty_peripheral_template_580.hex at address 20000000.
Hi daniel59,
Be aware that we use H-Link Lite in our development boards and I am not completely sur if we have ever used J-Link EDU Mini. Could you please try to download firmware into the SysRAM using Keil in order to make sure that your custom board is working correctly? Only one of your boards has this problem or all of them?
Thanks, PM_Dialog
Hi, PM_Dialog
使用keil将固件下载到Sysram进入调试会话吗？
只有我的一些董事会有这个问题......
sometime the log shows Could not start CPU core. (Error code: -1).
and some boards after I tried and tried it can be connected by SPI Flash programmer, but then next time failed. As the attachment log show.
Will the length of cable I use to connect my boards with J-link affect the connection?
Daniel
Hi daniel59,
Could you please check that you configured correctly the SPI Flash pins from the “Booter & Board Setup” tab of SmartSnippet? The “SPI Flash pin configuration” should be according to your board connections. You mentioned that you are able to connect to the SPI Flash, so when the procedure failed when trying to read or write the flash? The length of the cables might be an issue, so try to use shorter cables. Regarding the SysRAM, yes, I meant to download your firmware using the Keil. It’s a little bit strange behavior, so this might be a hardware issue on your PCB. Also you mentioned that only some boards have this problem, so let me ask you something for a clarification. Except those boards, could you please let me know if you have any completely functional boards (connect, read, write SPI Flash, bootable, and start advertising?
Thanks, PM_Dialog
Hi, PM_Dialog
使用keil，当我运行代码时，使用ble_app_barebone项目，它转到代码：
if ((GetWord16(SYS_STAT_REG) & DBG_IS_UP) == DBG_IS_UP)
__asm("BKPT #0\n");
The SPI flash error I mean is, for example, this time I press connect it shows success, next time I press connect it shows fail.
And yes I have a completely functional boards, it can be connected correctly. So I think J-link device is working well.
Daniel
Hi daniel59,
This means that somewhere your application code gets stuck either to NMI_HandlerC or to HardFault_HandlerC. Could you please clarify where if gets stuck? I have recommended you a tutorial for how you are able to find the reason of the NMI / HARDFAULT. Since you have functional boards and you run some code, I suppose that some of your boards have hardware issue.
Thanks, PM_Dialog
Hi PM_Dialog,
是的，我尝试了Tutorial 8，2种方法都不工作。
Show callee just jump to the __asm("BKPT #0\n");
and the MSP method shows address 0xFFFF0000; which is MOVS r0,r0
maybe because of my custom j-link device?
and is there any method to detect whether bad chip or bad board?
Hi daniel59,
您是否检查了引导加载程序是否正在执行，以便验证580是否正常运行？您可以探测P04和P05引脚，并且应切换引导程序的一部分的引脚，因此在连接到终端时，您应该看到设备打印垃圾。
