DA1458X大规模生产

嗨rohit，

For mass production, please check the Production Line Tool (PLT). Up to 16 devices can be connected..

您是否使用此工具进行生产？

Thanks, PM_Dialog

嗨rohit，

Please check section 7.2.4 BD Addresses from the following document.

//www.wsdof.com/sites/default/files/um-b-041_da1458x_da1468x_production_line_tool_4v2.pdf

Could you please clarify what you would like to accomplish with BD address? What is your requirement in production?

Thanks, PM_Dialog

嗨rohit，

当使用PLT时，BD地址将被编程到OTP标题中。之后，设备将获取OTP报头的BD地址，因此将忽略NVDS中的任何其他BD地址或应用程序代码中的任何其他BD地址。在生产过程中，代码不会受到影响，但如前所述，在PLT将与适当的BD地址写入OTP标题之前。关于你的最后一个问题，请你澄清一下吗？请注意，OTP代表一次性可编程，因此不能多次写入。

Thanks, PM_Dialog

嗨rohit，

如果您计划使用PLT生产，并且如果要通过PLT刻录BD地址，则BD地址将存储在OTP标题的相应字段中。这个领域也可以在没有PLT的情况下烧毁，所以如果您有大量的电路板，您可以进行一些测试。您可以使用“使用SmartSnippet”工具箱来读取和编写OTP标题。

>>>如果我使用Flash进行生产，那么效果是多少？

如果将BD地址编程到OTP标题？因此，如果我正确地理解您的设计中使用DA14580和DA14583，您是否想通过PLT进行编程（使用不同的FW假设）？那个BD地址怎么样？

Thanks, PM_Dialog

嗨rohit，

In all cases, if you are using the PLT to burn the BDA, then it will be stored in the OTP Header. Then the DA1458x will start advertising with the BDA from the OTH Header. Please check nvds_read_bdaddr_from_otp(). Do you mean to burn the BDA in the OTP Hader and then read it from you FW?

Thanks, PM_Dialog

嗨rohit，

如果device BD Address is written in OTP header the CFG_NVDS_TAG_BD_ADDRESS value is ignored. If you check the system_init() function, then you will see the SDK checks and reads the BD address - nvds_read_bdaddr(). If you check the aforementioned function, you will see that :

如果da14583，sdk首次检查并读取来自da14583的内部spi flash - nvds_read_bdaddr_from_da14583_flash（）的BD地址..如果在Flash中没有找到BD地址，则尝试从OTP - NVDS_READ_BDADDR_FROM_OTP（）读取BD地址。

In case of DA14580, as it does not contain an embedded SPI Flash, the SDK checks only the OTP Header - nvds_read_bdaddr_from_otp().

If you read the source code of nvds_read_bdaddr_from_otp(), you will see how to read the BD Address form the OTP Header which starts from 0x7fd4 address (BDADDR_OFFSET).

Thanks, PM_Dialog

嗨rohit，

The otp_bdaddr is mem-copied in the dev_bdaddr.

memcpy(&dev_bdaddr, otp_bdaddr, sizeof(dev_bdaddr));

If you search a little bit in the SDK, you will find the following:

///设备BD地址

struct bd_addr dev_bdaddr __attribute __（（部分（“retent_mem_area0”），zero_init））;

The otp_bdaddr is already retrieved by the SDK. So, this is up to you – you can use this function or implement you own function based on nvds_read_bdaddr_from_otp(), All you need to do is to read the correct address from the OTP.

Thanks, PM_Dialog

嗨rohit，

Sorry, bur I am little bit confused, so could you please indicate what you are trying to accomplish? Did you burn the OTP with your firmware, or did you burn the OTP Header with a specific BDA? Just try to connect to the OTP Header from the SmartSnippets Toolbox and burn your BDA.

Still I am not completely sure if I have understood your requirement. If I understood correctly you have 2 different products. The first one in based on DA14580 and the second on the DA14583.

You would like to use the PLT and burn the OTP Header with a specific BDA. For testing purposes, you can use the SST in order to burn the BD address. Did you burn the OTP Header?

Thanks, PM_Dialog

嗨rohit，

延迟道歉。广泛的rnign the dev_bdaddr could be a possible approach. The device obtains the bd address during start up, in the nvds_read_bdaddr() function (the device checks from the where the bd address can be obtained either NVDS structure or OTP) and places the obtained value in the dev_bdaddr variable that holds the address of the device.

Can you please clarify #3 step?

>>>在User_Peripheral文件中 - 使用dev_bdaddr-> addr [5];访问的地址并分配在广告变量中

你的意思是你想在广告字符串中添加BD地址吗？

正如我已经提到的那样，您应该在OTP标题中刻录BD地址。请使用智能代码段工具箱才能读取和刻录OTP标头。您不需要将整个应用程序图像刻录到OTP并从那里启动

Thanks, PM_Dialog

嗨rohit，

Sorry, probably I missed your last comment. Do you mean the steps you should follow in order to burn the BDA in the OTP Header through the Smart Snippets Toolbox?

如果是，则可以使用CLI才能刻录OTP标题中的BD地址。CLI可以在\ 5.0.4 \二进制\主机\ Windows \ prod_test_cmds SDK路径下找到。以下命令将BD地址写入OTP：

prodtest -p otp wr_bdaddr

example: prodtest –p 14 otp wr_bdaddr 44:49:41:4c:4f:47

Another option might be to use the SmartSnippets Toolbox in order to burn the BD address in the OTP Header. Generally, for burning the OTP through the SST you should the OTP Programmer. Keep in mind that the latest version of the tool is recommended .

The OTP has 3 areas where the user can burn data:

• The OTP image area, where the user code is placed and mirrors to the sysram at boot.
• The OTP NVDS area, where the NVDS structure is populated with the OTP at boot.
• The OTP Header area, where flags and specific values that define the operation of the device are placed (more information regarding the values of the OTP Header can be found in the Smart Snippets User guide).

When burning the OTP, you should make sure that the programming voltage is clean and must not exceed 6.8V. Please refer to the datasheet to find more details for the programming voltage. Keep in mind that OTP stands for One Time Programmable, thus you can’t erase and re-write the OTP multiple times, but you can only flip the bits that are still set to 0 and turn them to 1.

在你的情况下,开放对海温和连接the OTP Header. As soon as you are connected, you will see the all the available field in the OTP Header. The PLT will store the BD Address in the following address in “Device unique ID” fields.

因此，如果您想测试它，您应该在“设备唯一ID”字段中刻录BD地址。请注意，单词中最重要的（最左）字节存储在最小的地址（Big-Endian）中。例如。如果字段'设备唯一ID'的用户类型0a0b0c0d，0x0a将写在0x47fd4，0x0d将写入0x47fd7。
