Hello,
I am just trying to program the EEPROM using smart-snippets. However, every time I programmed it and restart the device nothing happens.
If I program the EEPROM (M24M01-DFCS6TP/K) with burn and verify everything seems well. If I then read the EEPROM using the 'READ 32KB' button it still shows it. However, as soon as I press reconnect the data is gone.
Is there anything I have to consider? I attached you two screenshots.
what is jtag_programmer.bin?
Here's the log file:

Hi afkiwers,
请尝试用逻辑分析仪探测I2C信号，并检查DA14580和EEPROM之间交换的数据。另外，我强烈建议您将EEPROM与SDK的i2c\u EEPROM一起烧录，并尝试读取一些数据，然后检查固件是否保留或内存是否为空。jtag公司_programmer.bin 当你要通过JTAG对你的设备进行编程时，flashu程序员下载的二进制图像。对DA14580编程的第二种方法是通过UART，因此在这种情况下，flash\U程序员将下载flash_programmer.bin 二值图像。
Thanks, PM_Dialog
Hi,
什么是SDK的i2c\ U eeprom。我使用EEPROM的程序员选项卡。我现在有点困惑。
Kind regards
Hi afkiwers,
The i2c_eeprom is a demo example of the SDK which demonstrates how to initiate, read, write and erase an I2C EEPROM memory. The project is located in the projects\target_apps\peripheral_examples\i2c\i2c_eeprom SDK directory. So, my suggestion was to burn your EEPROM with this firmware, and try to read some data in order to check that read functionality works correctly. For getting more information for i2c_eeprom example, please read the section 7.19 I2C EEPROM Example of theUM-B-050 : DA1458x Software Developers Guide (SDK5)from our support page.
When you using Smart Snippets to burn the SPI Flash or the EEPROM from the appropriate tabs, you have two option to do that, through UART or through JTAG interface. Smart Snippets doesn't support any kind of flash by default, when you hit the connect button when trying to program the flash/eeprom there is a small firmware that is downloaded into the 580 called flash_programmer.bin in case of UART or jtag_programmer.bin in case of JTAG. As I am able to see from your log file, you are using JTAG interface. So the jtag_programmer.bin is the binary image that is downloaded from the tool when you are going to program the EEPROM through JTAG. You can find the flash programmer project in the following path of the SDK: DA1458x_SDK\5.0.4\utilities\flash_programmer
