Hi

Since I had a sample FreeRTS Project for CY8CKIT-044 (Flash 128KB, SRAM 16KB)

I changed the device to CY8C4247LQI-BL483 (CY8CKIT-042-BLE) and added a BLE module

in the schematic. I only called CyBle_Init() and did nothing more with BLE.

First the good news is, yes, I could compile the project and FreeRTOS seems to be working!

Second the bad news is, the device is almost FULL!

011-Build-Done.JPG

It says the SRAM used is 99.1% !

So I wonder if we can do any useful thing on top of this.

I would recommend you to get and use CY8CKIT-042-BLE-A,

which has CY8C4248LQI-BL583 (Flash 256KB SRAM 32KB),

So that some more things can be done 😉

Hi Motoo,

As your recommend, I change device to CY8C4248LQI-BL483, then build it succeeded.

Output as follow:

Flash used: 96730 of 262144 bytes (36.9%).

SRAM used: 22640 of 32768 bytes (69.1%). Stack: 3072 bytes. Heap: 1024 bytes.

Thanks !
