If you want to use a power bank you should do some handmade modification in the PCB, because as I mentioned in my previous post, the power bank doesn’t do any enumeration by default, so you will not be able to supply the chip with 3V. If you don’t want to modify the PCB, you are able to use the battery as an external power supply, but you should be aware of the power consumption of your application. Regarding your second question, you are able to download firmware in all of them. When you download firmware into the sysRAM, be aware that if the board resets or power off, the code will be lost, so you should download it again. If you burn the OTP, you are able to program your chip once, and then you will boot only from OTP. Also, you can download firmware into the SPI Flash, and the code will be retained after the reset or power off.
嗨,vishnuatdialog,

您好,对话
我希望单独使用开发板(枚举传感器数据)在使用智能片段工具通过UART倾倒HEX代码后,单独使用USB电源输入。
如果我想要这个,我该如何为模块供电,以及可以将十六进制代码倒入开发板(MB+DB)的位置?是在Flash还是OTP还是Sysram中
谢谢
