我对用于将DA14586连接到外部设备（MSP430）的引脚，用于从串行接口启动（我想使用SPI接口）。
我读取了AN-B-001“从串行接口启动”，并看到引导引脚分配（步骤1 / SPI Master）为P0_0 / SCK，P0_3 / CS，P0_5 / MOSI和P0_6 / MISO。这似乎足够明显，但我在DA14586数据表中阅读的东西让我困惑。Datasheet说：“在引导顺序期间，端口P2的四个SPI引脚用于访问内部闪存”（P2_0 / CLK，P2_3 / EN，P2_4 / DO，P2_9 / DI）。这听起来有点像我一样。数据表是否告诉我有关不同的功能？
Once I've booted the DA14586 using the serial interface I'd like to control the DA14586 using the same SPI interface. Is that possible?

嗨TP2017，
586附带嵌入式闪存，OTP报头被预编程，以便使用OTP标题中的“引导特定映射”字段从嵌入式闪存的引脚启动。AN-B-001文档涉及580/581/583系列，启动程序是相同的，但不完全相同，嵌入式闪光灯附带的586不遵循与583相同的架构（也是配有嵌入式闪光灯）。因此，在585/586案例中，在附录G中的文档UM-B-079 DA14585_586 SDK 6软件平台参考文档中介绍了引导过程。因此，究竟究竟是如何从内部闪存中触摸启动（如OTP标题中的适当字段指示）在未从内部闪存中启动后，它将开始执行UART序列，因为它在附录31中描述并继续其余引导协议。启动FW后，您可以根据需要使用引脚。
Thanks MT_dialog
谢谢你的回应。我仍然不知道阿布t the pin assignments, though. Appendix G of the UM-B-079 DA14585_586 SDK 6 Software Platform Reference lists P0_0/SCK, P0_3/CS, P0_6/MISO, and P0_5/MOSI for the Step A boot process. I also noticed the same pinout designated on Table 21 of the DA14586 datasheet. However, I on Table 1 Pin Description (p. 19 of DA14586 datasheet) it shows P2_0/SPI_CLK, P2_3/SPI_EN, P2_4/SPI_DO, and P2_9/SPI_DI and has a comment "Note: During the boot sequence, the four SPI pins of port P2 are used to access the internal Flash memory. Therefore these pins shall not be remapped or used for any other purpose.". That is the part that confused me. I'd like to be sure I haven't misread the documentation and assign the wrong pins before I commit to a board design.
Thanks
嗨TP2017，
如上所述，585和586的引导加载程序是相同的，这两个设备之间的差值是586具有内部闪光，以便存储代码，因为它具有内部闪光，并且大多数可能是用户想要的存储一些代码，由于此OTP特殊标志引导ROM代码不会直接执行串行引导过程，但它将首先检查在该字段中声明的特殊引脚上的SPI接口，如果它无法从中启动它然后将继续执行串行引导。当设备从外部闪光灯找到FW时，它将将代码镜像到585的RAM，引脚将根据您的FW重新映射，但是启动过程将结束，镜像过程将完成，因此您不会再次访问闪光灯以获取读取代码，但为了读取Flash的任何数据，您需要将FW的引脚配置为SPI引脚，以便访问内部闪存。但是，请注意，如果您计划在这些引脚上连接任何外部传感器，则应确保它们不会与引导一起使用
procedure.
Thanks MT_dialog
which serial boot pinout?
I think I understand your last comment, but I'd like to be certain before I order a prototype board.
I'm looking for the specific pinout for serial booting for the DA14586. Is it P0_0/SCK, P0_3/CS, P0_6/MISO, and P0_5/MOSI (Table 21, p. 45 of datasheet) or is it P2_0/SPI_CLK, P2_3/SPI_EN, P2_4/SPI_DO, and P2_9/SPI_DI (Table 1 p. 19 of datasheet)? The datasheet seems to contradict itself.
（从表1，p.19：“注意：在引导序列期间，端口P2的四个SPI引脚用于访问内部闪存。因此，这些引脚不得重新映射或用于任何其他目的。”）这意味着P2 SPI引脚用于DA14586上的串行引导？
Thanks
嗨TP2017，
如上所述，586使用与585相同的引导加载程序，因此引导加载程序过程完全相同，但由于586具有嵌入式闪存，因此OTP标题字段引导特定映射从出厂刻录，以便首先从P2_0启动/ spi_clk，p2_3 / spi_en，p2_4 / spi_do和p2_9 / spi_di，如果失败，它将转到并执行标准引导加载程序过程。我承建了数据表有点令人困惑，因为它描述了标准序列，而不是烧毁的OTP字段的586选项，将与数据表的作者一起检查。
Yes, that is what i ve been mentioning throughout the post.
Thanks MT_dialog
Thank you very much for your help.
你好
I am using DA14586 with internal flash . And one of my sensor is connect to da14586 through spi interface as this P0_0/SCK, P0_3/CS, P0_6/MISO, and P0_5/MOSI.
I am configuring these spi pins like this GPIO_ConfigurePin(GPIO_PORT_0, GPIO_PIN_3, OUTPUT, PID_SPI_EN, true);
#if 1
ARCH_PUTS（“测试1 \ n \ r”）;
#endif
GPIO_ConfigurePin(GPIO_PORT_0, GPIO_PIN_0, OUTPUT, PID_SPI_CLK, false);
#if 1
arch_puts("test 2 \n\r");
#endif
gpio_configurepin（gpio_port_0，gpio_pin_6，输出，pid_spi_do，false）;
#if 1
arch_puts("test 3 \n\r");
#endif
GPIO_ConfigurePin(GPIO_PORT_0, GPIO_PIN_5, INPUT, PID_SPI_DI, false);
但它没有启动。
所以，我如何通过SPI使我的传感器接口或者是什么是正确的竞争来做这件事。
感谢和问候

嗨Jasmeet Singh，
Is there any specific reason why you are using that GPIO for the sensor? Did you try to connect it in any other GPIOs?
Thanks, PM_Dialog
你好
In page number 45 TABLE no. 21 of datasheet (DA14586). They have given Peripheral Pin Mapping for spi master that is the reason we are using these gpios as spi lines for our sensor.
no we did not try with other gpios.
感谢和问候

嗨Jasmeet Singh，
This is the booting sequence as the BootROM checks specific GPIOs in order to boot from different serial devices. In general, you can use any GPIO as SPI - you will need to configure it in your firmware too. In the meanwhile, could you please probe the SPI signal with a logic analyzer tool and share a capture?
Thanks, PM_Dialog
