CC3220MOD: CC3220MOD (Without 1MB OnChip Flash) in place of CC3220MODSF(With On chip flash 1MB)

Part Number: CC3220MOD
Other Parts Discussed in Thread: UNIFLASH

We are currently using CC3220MODSF module on our board and now we are planning to use CC3220MOD module.

Currently We program modules by setting SOP Pins for UART Load, using Uart and Reset pins from Launchpad kit and Uniflash Utility.

As per our knowledge All CC3220MOD Modules have Serial Flash Connected with Flash_SPI of Chip.

Can we directly use CC3220MOD(Without 1MB OnChip Flash and having Serial Flash) in place of CC3220MODSF? If we use CC3220MOD, Then can we use same method for programming (Uniflash and UART Pins of Launchpad kit)?

    Hi,

    Yes, you can use CC3220MODS by same way as your CC3220MODASF. This module have inside same 4MB SPI flash. Programming workflow be same as well.

    But be aware that you will need to compile your code for execution from RAM instead from XIP flash. This can be achieved by changing linker file from SF to S device. In case of S device is code executed from 256kB RAM. Into this RAM need to fit all your code, variables, buffers, stack, heap...
