我们这儿使用的TPS65981的芯片,参考的TPS65981_EVM板绘制了电路原理图,现在有几个疑问:
1、我们通过TPS6598x Application Customization Tool配置好了,保存得到两个bin文件,分别是low region和full flash image,如果向外挂的flash烧写bin文件的话,应该选择哪个bin文件?
2、保存bin文件的时候,TPS6598x Application Customization Tool提示region 1 offset和region 2 offset怎么设置,是否使用默认的设置0x2000和0x12000?
谢谢!
Star Xu:
The function of updating the SPI Flash contents over I2C will only work once there is already a valid configuration image inside the flash. In other words, the TPS65981 has to be fully booted and in "APP" mode for this function to work.
Make sure you are using the "Full Flash" .bin file when you are updating the SPI Flash. Once you have a valid full flash image onto the TPS65981, you can double check that it is functional by checking the Mode register and reading back "APP".
Once your TPS65981 is fully operational, you can then use the Low Region .bin file to update the contents of the SPI Flash over I2C.

您好!
感谢你的回复,还有一些疑问,麻烦你帮我解答一下。
1、我使用TPS6598x Application Customization Tool配置完成之后,生成了 "Full Flash" .bin文件,如下图
然后下一步保存,会提示我设置region 1 offset 和 region 2 offset,如下图
这个offset怎么配置,还是选择默认配置就行?
2、我们烧写flash没有使用TSP65981EVM上的FTDI模块,而是使用了普通的SPI flash烧写工具,请问烧写的首地址有没有特殊要求?
谢谢!
