亲爱的对话支持，

我们正在使用新的Inventek ISM14585模块。我们想将MSK固件移植到这个模块，使用BMI160(稍后添加BMM150)。在MultiSensor DK上，我已经成功地用BMI160替换了acc/陀螺仪，并使其运行。

现在我移植固件有一些麻烦。

观察:

(1)我必须undef USE_SPI_FLASH_CONFIG，否则我得到一个硬错误(等待SPI读取flash)。我不知道有什么问题。ISM14585的内部闪存是一个GigaDevice GD25D系列。

(2)我已经停用了env的大多数程序。传感器和磁力计。当我启动固件和联系的物联网应用,UART显示如下:< / p > < pre > <代码> = = = = = = = =物联网+开始= = = = = = = = INFO:传感器Initilization信息:传感器暂停信息:阿德开始,值:160信息:物联网互联信息:传感器Initilization信息:传感器暂停信息:DWS cmd: 21信息:DWS cmd: 22信息:DWS cmd: 11信息:DWS cmd: 1信息:传感器开始信息:DWS cmd: 17信息:DWS cmd: 13信息:DWS cmd: 20信息:DWS cmd: 26日< /代码> < / pre > < p >之后,什么也不会发生。该应用程序不显示任何传感器数据。

Findings:

(A) I measured that the BMI160 interrupt is constantly high, it seems the DRDY interrupt is not working.
Apart from that, I see CS, CLK, MISO, MOSI without any abnormalities.

(B) In UM-B-101, appendix A, I discovered that the MultiSensor DK actually uses a secondary bootloader that takes care of some configuration steps; but it did not seem to me that it does anything crucial for BMI160 (whereas it does some configuration for the original acc/gyro).
In the ISM14585, OTP is burned with a secondary bootloader since the internal flash CS is mapped to P0_7 instead of P0_3 (thus it would not boot from in dev mode without this).

My Questions:

(1) What can be the reason that I don't see the interrupt from BMI160 going low?
(2) Is the special secondary bootloader necessary? Can I port the firmware by just flashing the resulting hex file into the flash?

Your help is very much appreciated.
