I want to know how to manually OTA.

我执行了以下步骤：

1. Write flash pxp_reporter.bin to 0x2000 and write new_pxp_reporter.bin to 0x2002000 by cli_programmer.

2. modify CACHE_FLASH_REG to 0x16102006(origin is 0x16009006) by Jlink("w4" command to modify it), and restart.

But it didn't work. The value of CACHE_FLASH_REG reset to 0x16009006.

How to do can change the remapp adress to 0x2002000? My goal is to switch images(active and upgrade image) in flash by modifying variables. How to do?

谢谢。

DA14695 Development Kit – USB resets after USB extracting

Hello Dialog,

I have combined two examples from SDK: PXP reporter and USB SMSD. I implemented a charging profile for my battery and connect the battery to J5 port. I have jumpers on J2(2:3) and J3(2:3). All works well, but when I insert/extract DevKit from USB port, DevKit reboots. Similar situation with powerbank( stucks at insertion/extraction). When I leave DevKit inserted and manually connect J2:2 and J2:3 all works well. What is may be wrong?

Thank you.

binary too big if emwin font is included

When using emWin library, if I use GUI_DispString() or other font-involved function, the binary size is easily overflowed and get the following errors.

ld.exe: xxxx.elf section `.text' will not fit in region `ROM' ld.exe: region `ROM' overflowed by 48864 bytes

How can I make font data not to use .text section?

Is there any guideline?

How to use emwin library properly

Hi, teams.

I have ported emWin library to my project, and create a new diplay driver for my board.

为了测试显示，我从如下示例中复制了非常简单的代码：

GUI_Init（）；桂色（桂白）；桂色（桂黑）；GUI_Clear（）；桂圆（40,40,40）；

GUI_Init() returns successfully, and screen_power_on(), screen_setup(), and screen_enable() functions are properly called.

But, GUI_Clear(), GUI_FillCircle() functions never works.

L2CAP bandwidth

Hello,

I put together a bandwidth measurement test using L2cap channel (credit based, etc).

我设置PHY 2M，DLE 251字节，一个中央，一个外设，一个L2cap通道。我改变了连接间隔和mtu大小（高达2500字节），但我得到的最大值是大约1Mbit/s. (with high mtu and 6 connection interval)

I was wondering if the current value I am getting is the maximum or is some of my settings off? Should I expect GAT services to be faster?

谢谢，

Firmware(.hex file) which modifies internal capacitance for crystal

Dear Dialog,

I am trying to evaluate crystals and checking its performance with DA1469x.
Where can be found the firmware (or .hex file) in SDK 10.0.6?
Or if I need to compile the code to create .hex file, which project file should be compiled to oscillate the crystal?

In SDK for DA14585, I was able to find the firmware called "prod_test585.hex" which can be applied to oscillate various crystals and change the internal capacitance.
I would like to do the same oscillation test with DA1469x.

谢谢。

Unable to transact using I2C with MPU6050

Hi All,

I am trying to read the value of the WHOAMI register of MPU 6050 using I2C interface. I was unable to find a function directly for register R/W. so, using the adapter, i have used this code.

eeprom\数据\读卡器（eeprom\ 24FC256，0x75，page\ buff）；

Page_buff is empty and will receive the values after reading.

tatic uint16_t eeprom_data_reader(i2c_device dev, uint8_t pageAddr, uint8_t *buff)
{
uint8_t e_addr_buff[1];
