CCS/CC3220: Use driverlib from ROM

hi,

I have a question now. To save RAM space, use the peripheral driver interface in the external ROM. The SDK uses the simplelink_cc32xx_sdk_2_10_00_04 version, according to the SWRU464 document 6.2 description, modify and recompile the relevant libraries and their own projects in the SDK. When running the new bin file (when the bin file is burned, the service pack bin file is burned together) Some strange problems occur, such as a sudden restart during operation, when the MAP_PRCMHibernateCycleTrigger() interface is called, it is stuck, and after the power is turned off again, it is the state after the interface is running. What is the cause of this?
Is the driverlib library in ROM the same as driverlib in RAM, or is there a difference? If so, is there any documentation?

HI Feihu,

Please read: dev.ti.com/.../CC3220_ROM_services.html
USE_CC3220_ROM_DRV_API should already be defined in the .mak file for the drivers. You may have broken something inadvertently by changing something

Hi Aaron,
As you said, there is no need to modify the libraries in the SDK, just recompile. Then, modify and compile my application project as documented.
Is the driverlib in the ROM the same as the program loaded into the RAM?

The driverlib inside ROM corresponds to driverlib version 1.50.1.00, so there are some differences between it and later SDKs
