Hi There, Thank you for the reply. Please find attached the mrom_otp_lock_check.ttl You can use this with Tera Term to check if the OTP is locked. 
 anand said: is secure boot is the reason for this error? 
 Yes, I believe that secure boot could end up on this error. mrom_otp_lock_check.zip Open Tera Term, select the correct COM port for UART0 Debug Interface, set Baudrate at 230400. Reset your device via the switch and then type 'reset' so it goes into the MROM menu. After that go on Control-->Macro And navigate to find the mrom_otp_lock_check.ttl in order to select it. Let the ttl run and you should be prompted with a message. In case you are not able to disable the secure boot feature or use the launchers (from e2 studio) to program your DA16600, you can do it manually from Tera Term. Let me summarize the steps here: 1) Open Tera Term and Connect to UART0 Debug Interface with Baudrate set at 230400. 2) Reset your device via a Switch and then type ' reset ' to get into the MROM menu. 3) First Upload the FBOOT image by typing 'loady 0 ' It should like this: Then go into File -->Transfer--> YMODEM --> Send... Navigate and find the FBOOT generated image. Note: In case the Transfer is not happening, please reset the custom board and try again. Finally when the FBOOT is uploaded you should see the following: 4) Now follow similar procedure for the FRTOS generated image by typing ' loady 23000 ' It is the exact same steps to download the FRTOS generated image. 5) In order to download the DA14531 generated images you should type " loady 3ad000 1000 bin " and then follow the same steps to find, select and download the DA14531 image via YMODEM protocol to the DA16600. 6) When all Images ( FBOOT, FRTOS, DA14531) have been succesfully downloaded, you can type ' reboot ' and the DA16600 will load them. This is the same procedure the launchers on e2 Studio do as well. The launchers just run some extra checks before trying to download the Images. Best Regards, OV_Renesas

Hi There, Happy New Year! Thank you for posting your question online. This is a known issue, caused by the DA14531 SW Reset not being able to be detected. Please find attached the DA16600_ble_sw_reset_fix.patch and apply it on the FreeRTOS SDK v3.2.8.1. 
 
 The BLE SW reset should be checked and then rebooted. 
 The BLE SW reset should do before the flash related functions because it takes some delay to send BLE SW reset command. 
 After fix/updating with the patch, the BLE related booting error was fixed. 
 
 Please share any feedback! P.S. The patch will be included in the next SDK release. Best Regards, OV_Renesas 
 DA16600_ble_sw_reset_fix.patch

Hi There, Thank you for the reply. Please download the FreeRTOS SDK v3.2.8.1 . Unzip it and place it on a new folder. Download any Git Terminal Interface you want. Place the patch inside the SDK as shown below: Open the Git Terminal inside your SDK folder and type: git init

git add .

git commit -m "Initial Commit of FreeRTOS SDK v3.2.8.1"

patch -p1 <DA16600_ble_sw_reset_fix.patch
 Final result: As you can see, the 2 final changes were not applied. You can easily apply them by opening the Patch folder (with Notepad++ or any other program that can showcase code). Go to the end of the file: 
diff --git a/core/system/src/common/command/command_net_sys.c b/core/system/src/common/command/command_net_sys.c

 As you can see, we want to apply changes on the command_net_sys .c file which is placed on the path above. The lines with "+" means that you will have to add this line of code and the lines with "-" means that you will have to remove this line of code. Go on your SDK folder and search the command_net_sys.c file to make the changes manually. You will need to add manually 3 lines of code and remove another 4 lines on the same file. In case you do not want to use Git, you can easily open the patch and go through the changes manually. We hope this could helpful! Best Regards, OV_Renesas

Hi There, Thank you for the reply. After you have applied the patch, please follow the steps below: 1 ) Refer on the UM-WI-056 Getting Started Guide. 
 On Section 5. Software Development Kit, on page: 34 You will need to download e2 studio 2023-07 (v23.7.0) or later. Link is available on 5.3 Installing e2studio IDE. Please follow the steps of the Getting Started Guide. 2 ) After the e2 studio installation, open the e2studio and declare your SDK folder as your workspace as shown below: 3 ) When the e2 studio opens, close the Welcome screen by the Hide button or by clicking on the X as shown below. 4 ) Import the da16600 getting started project as shown in the section 5.4 Importing DA16200 FreeRTOS SDK Project into e 2studio of UM-WI-056 or as shown in the screenshots below: Make sure you have selected the da16600 getting started project and the SDKJFlash project as shown below Click on Next> and on the next window select DA16600 as your target device. 5) You should be able to see the 2 projects on your Project Explorer: 6 ) Before building your project, right click on the Project Explorer tab and select Import... 7) Now, if you hover over the Run External button you can see all the available launchers we have imported to program/erase the DA16200/DA16600 8) Right click on the da16600 project and select Clean and then Build project During the first Build process, the Generate Configurations for Windows launcher will be executed. You will have to select the Flash memory on your custom board or the one inside the Dev Kit. If you select wrong, you can easily go through the Run External button shown on step 7 and launch the configuration manually again. 9) After the Build procedure has been finished, you should see the results on the Console window and the generated images should be placed inside the img folder 10) I am using the DA16600MOD EVK v4.1, I have connected the USB to my PC and I select the uart_program_boot_rtos_ble_win launcher to program my EVK with the generated images. 11) On the Console Window you will have to select the correct COM port. The lower COM port corresponds to UART0 Debug Interface and the other COM port to UART1 which is being used for AT commands (if you have enabled this feature inside the SDK). I select the correct COM port and the image of the DA14531 I wanted to download (for peripheral or central). The whole communication has been attached below: uart_program_da16200 Version 1.0.6
0. COM40 - USB Serial Port (COM40)
1. COM41 - USB Serial Port (COM41)
2. COM55 - Standard Serial over Bluetooth link (COM55)
3. COM56 - Standard Serial over Bluetooth link (COM56)
Please enter number in the list of your COM port and press enter.

 You have now successfully flashed the DA16600MOD with the Getting Started project and the Patch applied. Note: All this steps are described on the UM-WI-056. I just shared some screenshots as well. Please refer on the Getting Started document as well. I hope this could be helpful. Please share any feedback if you are able to recreate the Hard Fault exception again. If you are still able to recreate the issue after the patch is correctly applied, please share the exact board you are working on so we can understand if there is a design issue (in case you have a custom board) or a dip switch issue (in case you have one of our EVKs). Best Regards, OV_Renesas

After reviewing the schematics, I noticed the RTC wakeup pin was connected with 3V3. Is this necessary? I removed that connection, and now I'm encountering a 'wrong image' error.

OV_Renesas · Answer

Hi There, Thank you for the reply. Please refer on the DA16600MOD Datasheet , on section 7. Application Schematic I do not see the necessary capacitors needed. For the DA16600MOD: 
 1 .Pin 28 (VBAT_3v3): Operating voltage 2.1V~3.6V (Typ. 3.3V), 10uF bypass capacitor 
 2. Pin51 (VBAT_BLE): Operating voltage 1.8V~3.3V (Max 3.3V), 10uF bypass capacitor 
 3. Pin 17,40 ( VDD_DIO1, VDD_DIO2): Check I/O voltage of MCU (1.8V ~3.3V). 
 4. Pin 27: Should be connected to GND as well. 
 
 We have also contacted your local FAE. They should reach out to you regarding your issue so you could share with them all the details. Best Regards, OV_Renesas

Hi There, Thank you for the reply. 
 anand said: can i get the contact details of local technical person 
 I have asked the local FAE team to share with me the contact details you are going to need. I will reach out to you directly when I have a response. In the meantime, please try to manually download, via Tera Term as shown in the previous answers, the images attached on the FreeRTOS_v3.2.8.1_Images.zip file. It is the default getting started project and it works as expected on my side on the DA16600MOD EVK. You will not need to change the FBOOT image. FreeRTOS_v3.2.8.1_Images.zip Best Regards, OV_Renesas

OV_Renesas · Answer

Hi There, Thank you for the reply. We received a similar question on our private platform from your Distributor FAE. We will provide you the answer we gave them: There are 2 known issues for the DA16600 in the FreeRTOS SDK v3.2.8.1. One is related to the BLE SW reset which is the patch you have attached and there is another issue with the WatchDog timer. Please find attached the DA16600_watchdog_repeated_log_fix.patch file. I applied the patch on the FreeRTOS SDK v3.2.8.1 and then compiled the DA16600 getting_started example (with AT commands enabled). Please find the attached the img.zip file which contains the DA16600MOD images. Please also find attached the DA16600_get_started_watchdog_patch.log file with the Logs when running the specific images. Note: Both patches will be applied on the next SDK release.

Hi There, 
 anand said: will AT cmd work in this image? 
 Yes, the AT commands feature has been enabled for UART2. This can be seen on the UART0 logs: >>> UART2 : Clock=80000000, BaudRate=115200
>>> UART2 : DMA Enabled ... Best Regards, OV_Renesas
