da14580无法启动
Posted by当80分 10回复亲爱的支持团队,
我的PCB原理图在附加。LP5900TL是一个150mA输出稳压器,VBAT连接到3.7V锂离子聚合物可充电电池。
我注意到,有时候BLE芯片无法启动。当它失败时,它不会在UART引导协议期间发送UART代码(STX = 0x02)(应用笔记DA14580 / 581/583从串行接口启动AN-B-001)
Is my power circuitry correct for DA14580? What is the maximum current consumption (peak current) when DA14580 boots up?
由于设计误差,RF传输线阻抗不匹配。这是启动失败的原因吗?
Thanks for your help,
当

亲爱的支持团队,
Do you have any ideas about the failure?
您的帮助非常感谢。

嗨,
Apologies for the delay. So, I guess the DA14580 is connected to UART and booiting from P0_2/P0_3 with baud rate at 115200.
由于DA14580被编程,并且您按照标准UART引导过程,根据AN-B-001,580应发送0x02(STX).I我无法看到为什么在引导时没有得到适当的字节。请尝试通过UART使用SmartSnippet Toolbox启动,并检查您是否能够使用Smart Spippets Booter启动。
您使用的是哪种工具来闪存DA14580?
谢谢,PM_DIALOG.

嗨pm_dialog,
Thanks for your reply.
In my application, DA14580 boots from UART P0_2/P0_3. It receives its FW from a host CPU at baud rate 115200.
DA14580's boot code has been pre-programed by Dialog. I do not flash it.
这种配置是否适合最终生产?
X2是一个16MHz晶体,±20ppm 10pf,它没有校准。
According to DA14580's datasheet, frequency tolerance of ±20ppm is good enough. Can you please confirm this?
谢谢,

嗨,
Can you please indicate which FW the DA4580 is running ? If you could provide more information about your custom design it would be very helpful. Please try to program the DA14580 with any of the SDK examples.
请查看表330:16 MHz晶体振荡器:推荐的操作条件da14580数据表。您应该使用这些规范选择XTAL。您使用的XTAL部件号是多少?
如果您正在启动新的设计或项目,我们将强烈建议进入DA14531或DA14585 / 586产品和SDK6.0.14,因为它更加提高。亚博电竞菠菜我们有很多代码示例和改进的文档,还有软件路线图支持。DA14580产品系列和SDK5没有任何软件路线图支持。

我们还有一个DA14531模块,即DA14531 SmartBond Tiny™模块!它具有很小的尺寸,功率非常低。按照下面的链接查找模块的数据表,文档和HW抵消:

嗨pm_dialog,
这是一个问题,我已经解决了它。谢谢你的帮忙 !
我还有一个问题。从UART引导是在开发阶段使用的意图。是否可以在生产阶段使用这种模式(即大规模生产)?有什么限制吗?
谢谢,

嗨,
你能澄清最后一个问题吗?请选中以下文档中的DA14580引导顺序:
您是否意味着OTP和应用程序标志被烧毁?
When the OTP is programmed and the application flags on the OTP header are also burned, the primary bootloader is disabled so the scanning procedure doesn't take place, thus you will not be able to boot from the SPI or UART or I2C. You will be able to directly burn your SystemRAM though JTAG as long as the OTP header field called JTAG enable flag stays Enabled. If the application flags are burned and the JTAG enable flag is Disabled then the device becomes inaccessible. Keep in mind that OTP stands for One Time Programmable, thus you can’t erase and re-write the OTP multiple times
谢谢,PM_DIALOG.

嗨pm_dialog,
我不想刻录OTP,因为DA14580固件可能会在我的产品中更新。
I want it to boot from UART. Is there any limitations when using UART boot in final product?
谢谢,

嗨,
所以,所以应用程序代码将进入系统 - RAM,设备将从UART引导?
您的设计中有外部SPI闪光灯吗?
谢谢,PM_DIALOG.
