39. Troubleshooting

39.1. Error “2nd stage bootloader rejected (-105)” on Connect or Booter

Should the following messages Could not connect to device. read from QSPI failed: 2nd stage bootloader rejected (-105) been noticed while executing SmartSnippets Toolbox commands, using the UART interface on a Basic DK, please follow the next steps to resolve the issue.

Step 1 : Install SEGGER Jlink v6.12i or later and Run JLink Configurator

Step 2 : Right click on the Jlink product detected and update firmware (if needed) Right click on the Jlink product detected and select “Configure”. In the pop up window select “Enable” in the Virtual Com Port options

Step 3 : Start J-Link Commander –> Confirm the firmware update Enter “wconf 0x8E 0xFB” in order to change the TX drive behavior Power-Cycle the hardware in order to apply the change

39.2. Error message on not supporting ARMv8-M architecture

This appeared on DA1469x but may appear on other families too. User tries to open a connection with JTAG and the following message occur:

_images/jlink_error_armv8-m.png

Figure 177 Error connecting with JTAG

If user press OK Toolbox opens with errors reading specific addresses.

  • Close SmartSnippets Toolbox application

  • From command prompt move into JLink installation folder and run JLink executable (JLink.exe for windows)

  • A popup message requesting firmware update should occur.

  • Press yes to proceed with firmware upgrade

  • Close command prompt and try to connect with Toolbox again.

39.3. Warning on CLI interface running from windows: WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx…

This is a known Java issue https://bugs.java.com/bugdatabase/view_bug.do?bug_id=6790382

It does not affect the SmartSnippets™ Toolbox functionality.

However, to get rid of this warning the user can follow these steps:

  • From Start Menu type regedit into the run search field.

  • Navigate to path HKEY_LOCAL_MACHINE\Software\JavaSoft (on Windows 10 the path seems to be here: HKEY_LOCAL_MACHINE\Software\WOW6432Node\JavaSoft)

  • Right click on the JavaSoft folder and click on New -> Key

  • Name the new Key Prefs

39.4. Firmware file in Hex format does not start running when downloading to the board

SmartSnippets™ Toolbox has its own hex file parser to convert .hex files into binaries before download then to the board.

If this fails try to download the .bin version of the firmware or convert .hex to .bin with the hex2bin utility available in installation folder e.g. C:\DiaSemi\SmartSnippetsStudio2.0.11\Toolbox\common_resources\firmware_upload\hex2bin.exe or C:\Program Files (x86)\SmartSnippetsToolbox\SmartSnippetsToolbox5.0.10\common_resources\firmware_upload\hex2bin.exe

39.5. Error message during verification after erase or burn

Check that end address do not exceed real physical memory length.

39.6. Timeout error when working with large flash memory on JTAG

Tool uses a default timeout value of 10000ms when waiting for a response from the board on JTAG communication. This value is enough for e.g. a 8Mbit flash size. When working with larger flash increase timeout by editing file C:\Users\<user>\SmartSnippetsToolbox\properties.txt.

Add the following lines.

Code 12 Change JTAG communication timeout
JTAG_READ_TIMEOUT = 50000
JTAG_WRITE_TIMEOUT = 50000

A value of 50000 should be enough for a 32Mbit flash size. After changes, restart application.
