LAUNCHCC3235MOD: MbedTLS consuming code size, no room for OTA

Tool/software:

Hello,

I have successfully connected to an mqtt server the mqtt_client_example (without TLS and simplelink_cc32xx_sdk_6_10_00_05) and mqtt_client_over_tls_1_3 example (with using necessary TLS certificates and simplelink_cc32xx_sdk_7_10_00_13). 

But the problem is, i can make OTA using the SDK6 example with the image size about 200KB, but i won't do any OTA because SDK7 with TLS image size is 517KB (Actually it was 522KB and i disabled wifi direct feature).

.cmd file:

#define FLASH_BASE  0x01000800

When I look at the Memory Allocation window on the CCS, I see that .text.mbedtls consuming mostly on the FLASH.

TLS connection is successful, but there is no room for OTA.

How can I reduce code size? Can I disable some mbedtls features?

Best regards,
