production test on PAN1740

Hi mayrang,

当通过UART编程时，设备需要重置的原因是因为智能片段需要跟踪信号启动UART引导过程的0x02字节（从预定义的UART引脚）。因此，通过击中重置，设备开始执行引导加载程序，最终智能片段将捕获0x02字节并启动UART引导协议。显然，如果智能片段不稳定，它能够重置，那么它不会接收0x02字节，这意味着您的UART连接可能出现问题。

嗨Mayrarg，

The baudrate depends on which pins you are using, from your previous statement the P04 and P05 are operating over a 57600 baudrate, if nothing appears on any of the terminals that you are using (you should see garbage printing due to the bootloader running), then either the device doesn't reset (so no bootloader running) or there should be a connection problem with your UART. Also you mention that the CRC doesn't match for you, what exactly do you mean by that ? You download code and the device doesn't respond with 0x06 (ACK) or it doesn't match the calculation on the STM ? Also be aware that you should download the .bin file and not the .hex file (you should convert the .hex file into a .bin with the appropriate tool hex2bin.exe).

Thanks MT_dialog

嗨Mayrarg，

如果你想看到串行引导过程ure you do that via attaching a logic analyser on the bus. Since you are using the Smart Snippets tool it will automatically convert the .hex file that you are using into a .bin, so converting it yourself doesn't really matter (i was under the impression that you were using an external MCU in order to download code). Regarding the error that you get, i suppose that you are using a custom device, perhaps you should check the UART lines on your device apparently the data are corrupted generating an invalid CRC from what the Smart Snippets tool has calculated and what the device sends when the downloading procedure has ended.

嗨Mayrarg，

对不起，我很困惑，您正在尝试通过UART接口通过STM处理器编程Pan1740，并且它返回CRC不匹配或通过智能片段。从您所附的图像似乎您尝试通过智能片段尝试这样做并返回那种错误。此外，585 FW与上述问题有什么关系？Pan1740内部有一个580个设备而不是585.可以花更多的时间来描述您究竟想做什么，以便我能够提供帮助吗？

Thanks MT_dialog

嗨Mayrarg，

Bootloader位于ROM中，意味着所执行的操作是标准的，如果设备（580）将0x00作为CRC值发送0x00，则无法以某种方式交互或更改该代码，然后我假设没有实际代码下载，因此没有下载到设备中的实际字节（您是否能够使用分析仪检查，或者我认为您正在使用的平底锅以某种方式损坏。您能否请检查另一台设备并检查问题是否仍然存在。或者你能试图通过JTAG下载代码，而不是通过UART下载，并检查您是否能够这样做？

Thanks MT_dialog

嗨Mayrarg，

Either damaged or there is an issue on the SWD connections.

Thanks MT_dialog

嗨Mayrarg，

In order to disable the sleep mode you can set the app_default_sleep_mode to ARCH_SLEEP_OFF, but the fact that the device is in sleep mode doesn't mean that the device wont advertise. All the examples perform advertising even if they are in sleep mode, the device is sleeping between the advertising intervals, it doesn't sleep constantly. You wont be able to find why the device doesn't execute (you are not able to find the device over a BLE Scanner) just by downloading the fw over UART, i would suggest to use the JTAG connections and debug via keil, in order to find why that happens.

Thanks MT_dialog
