Hi,

Does anyone know how much free space there is left on KW38 running internal memory and included the OTA client feature?

Ok, but how big is the ota client part that need to be included in the app? Is it allocating all of the 256k-bootloader?

Hi,

The client mcu flash memory has two parts -- bootloader + ota client. At first, the bootloader will go to ota client to communicate with your server. The server send data to client and the client writes data to flexnvm(256k). When transfer completely, the client will go to bootloader and erase the ota client. Write the flexnvm's data to flash. Then bootloader will go to new application. So if your new program doesn't have the ota function, this example can only use once. The flash memory you can use is (256k - bootloader).

 

Have a great day,
TIC
