DA16200MOD

Hi AK,

Thank you for posting your question online.

       i have try to load this file  Download_W25Q32JW_FreeRTOS.ttl & mrom_otp_lock_check.ttl by using tera term VT but it taking so much time and not loaded in the module for that i am using

Were you able to see the progress bar on Tera Term? 
If there is no progress during the download please stop the procedure and try again.

ak said:

   what is the correct way to load the file and which one is correct.

Please refer on the UM-WI-056 DA16200 DA16600 FreeRTOS Getting Started Guide (renesas.com), on section 5.7 Programming Firmware Images in e2studio. and on section 5.7.3 Programming Firmware Images Using SEGGER J-Link


You can also find pre-compiled binaries on the DA16200 Product site: DA16200 - Ultra-Low Power Wi-Fi SoC for Battery-Powered IoT Devices | Renesas

hello,

           for the first time SDK load into module and then i check AT command ATZ to get OK command its not working 

        for this AT command have any  CR,CR+LF transmitted text setting.
 

     kindly give replay as soon as possible i am stuck in project.

thanks and regard's

Hi AK,

Thank you for the reply.

Yes, when you sent the AT commands you should also change the line. This is achieved with CR+LF. 
If this does not work, please probe a logic analyzer on the UART lines and share the catpure with us.

Hello,

                1) As you suggest the send the AT command with CR+LF.i did the same and also check the UART1 PIN connected with my scope but in that there is no waveform not generate i have attached the pic. 

                

   2) I have read in one datasheet there is external clock source required but in the schematic there is no pin i seen is it for another or the same. 

               3) Does the RTC required external clock source. because when i powered the RTC_PWR_KEY with VBAT  SDK is load but when i do it for next time SDK is not loading.is it because of RTC clock is not connected or is there any another reason.

i attached the PDF screenshot for this RTC clock issue kindly see any revert as soon as possible.

     Hello,

                 This is give me error CRC failed while loading.and i will check the AT command and this will not give me OK response.why this happen.

i did hardware connection the PDF application schematic show's

 like this ckt design i did hardware connection 
                               I did RTC_wake_up2-GND, VDD_DIO2 and VDD_DIO1,VBAT,RTC wake up,rtc pwr key give 3.3V.

Hi AK,

Thank you for the replies and apologies for the delay.

Based on the Screenshot you shared from UART0 on your next reply, the FW is not running and it is then expected that the AT commands will not work.

From my understanding, you are working with the DA16200MOD. 
Please refer on the DA16200MOD Design Files.
If you check the BOM List you can find the Oscillators:

And if you check the DA16200MOD Schematics:

The DA16200MOD includes the external clock source. If you have a design with DA16200 then you would need to add the external clock source.

It is clear that you have corrupted the FW stored in the DA16200MOD. 
I also do not understand the reason of issuing a 100bytes erase on address 0x22000, what was the goal?
I would suggest you erase the whole flash and then reflash your images. 
You should see on the UART0 logs a message that UART1 is initialized and after that you are able to sent AT commands:

>>> UART1 : Clock=80000000, BaudRate=115200
>>> UART1 : DMA Enabled ...

Hello Sir,

            Can you please tell me  How to erase the flash.
            Yes to get only DA16200MOD chip we are going to doing our own development of WIFI module 

      at which pin should i connect this both crystal because i have not seen any crystal pin indication which i early attached application schematic diagram.

Hi AK,

Thank you for the reply.

On the MROM menu if you write 'sflash erase' you will get the following:

To erase the whole Flash you should use 'sflash erase 0 400000'

DA16200MOD: Contains the external oscillators.

DA16200: You need to place external oscillators.

Hello,

               As you said i have to connect the external oscillator but you have attached the ckt for DA16200

and it have 42 pin and i have the module it have 37 pin and this don't have any oscillator pin connection.

can you please tell me the for which pin should i connect this oscillator which you given in previous chat.

Hi AK,

Thank you for the reply.
I am a bit confused.
Which device do you have? 
If you have the DA16200MOD, you DO NOT need an external oscillator.
If you have the DA16200 you WILL need an external oscillator.

hello,

     i am using DA16200MOD.
     ok.as you said it does not required external oscillator.
