DA14531 Dev Kit Hibernation Mode

嗨djames，

Thanks for posting on our public Bluetooth forum and glad that you’ve been working with our new Smartbond device. In the “Sleep Mode Tutorial”, there are 3 cases for the hibernation mode configuration (using SPI Flash/SysRAM/OTP). Can you please indicate in which case are you measuring 200-400 uA? If you are using SysRAM, is the debugger attached or not? In addition, which RAM blocks are retained? It would be very helpful if you were able to share those clarifications.

Thanks, PM_Dialog

嗨djames，

If the debugger (from the Arm Keil IDE) is attached, this prevents the system to enter any of the sleep modes. You don’t need to remove the debugger physically, just press twice the “Start/Stop Debug Session” button. Can you please indicate if the SPI jumpers are placed or not in the J1 header? Please, try to unmount the SPI jumpers. Then, I would suggest you to use the Power profiler from the SmartSnippets Toolbox and check if the device stops advertising and going into hibernation. In the Hibernation tutorial, advertising with 18second timeout is used, so the device will enter the hibernation mode after 18 sec.

Thanks, PM_Dialog

嗨djames，

你能试着用吗？DA14531 Configuring To hibernation modeSW example in order to set the DK into hibernation mode? Can you detect any change in the power consumption? All our SW example (including the hibernation mode SW example) don’t contain SDK, so you should link them with the SDK. Please follow the steps described in theSoftware Example Setup Using Python Link Scriptdocument.

Thanks, PM_Dialog

嗨djames，

我跑了这件事DA14531睡眠模式教程（HTML）并且冬眠电流在约1.8 ua。我使用DA14531 PRO-DK使用SmartSnippets Toolbox的电源分布器来测量。跳线如图5所示放置：带有JTAG跳线的硬件设置

1. Define the CFG_APP_GOTO_HIBERNATION macro in user_proxr.h

#if defined (__DA14531__) #define CFG_APP_GOTO_HIBERNATION

2. Comment out the following code snippet is snippets in user_prox.h

//＃如果已定义（cfg_spi_flash_enable）&&定义（cfg_app_goto_hibernation）// #error“config错误：无法定义cfg_spi_flash_enable和cfg_app_goto_hibernation。”//＃万一

3.开关在所有三个内存块和重新映射the address 0 to SysRAM as shown below:

#define cfg_hibernation_ram1 pd_sys_down_ram_on #define cfg_hibernation_ram2 pd_sys_down_ram_on #define cfg_hibernation_ram3 pd_sys_down_ram_on #define cfg_hibernation_remap remap_addr0_to_ram1 #define cfg_hibernation_pad_latch_en false #endif

4. In user_periph_setup.h file, configure the GPIO that would be used to wake-up the device from hibernation mode. In this case we have chosen P0_5 as the wake-up GPIO.

#f定义（__da14531__）#define hib_wake_up_port gpio_port_0 #define hib_wake_up_pin gpio_pin_5 #define hib_wake_up_pin_mask（1 << hib_wake_up_pin）#endif

5.在user_config中，将广告期更改为5秒。5SEC后，设备将停止广告并进入休眠模式。

static const strame default_handlers_configuration user_default_hnd_conf = {//配置默认处理程序//可能值所使用的通告操作：//  -  def_adv_forever //  -  def_add_adv_with_timeout .adv_scenario = def_adv_with_timeout，//在def_adv_with_timeout中配置广告时段。//它以定时器单元（3分钟）测量。使用ms_to_timerUnits宏将//从毫秒（ms）转换为定时器单位。.advertise_period = ms_to_timerUnits（5000），//配置默认处理程序的安全开始操作//如果启用了安全性（CFG_APP_Security）//可能的值：//  -  def_sec_req_never //  -  def_sec_req_on_connect .security_request_scenario = def_sec_req_nver};

6. Build the project.

7. Open the Power Profiler from the SmartSnippets Toolbox. You will need to connect via UART/SPI to enable the power profiler tool. Press ”Initialize” and “Start”

8.将固件下载到系统RAM中。

9.系统将启动5SEC的广告，然后它将进入休眠模式。请从我的设置中检查附加的屏幕截图。休眠Mod中的电流消耗约为1.8UA。如果休眠电流围绕此值，请使用工具测量它以便具有更好的测量。

嗨djames，

Many thanks for your valuable feedback. Setting the jumper on J8 pins 1 and 2, the C_TRIG triggered is enabled which is mapped on the P0_9. That pin is only available on QFN24 package! I have already the Team know about this and we perform some tests early next week. I will keep you updated on this!

Thanks, PM_Dialog
