SE050 library optimization

WorkerEmbedded — Mon, 15 Jan 2024 10:16:56 GMT

Hi everybody!

I've got just a little question about SE050 library and how can i optimize it.

My goal is to flash a project developed on LPC55S69 (it's like 610 Kb) inside another LPC55 with a 64 Kb dataflash.

My project was develop starting from a SE05X demo and now it's about 270 Kb.

The library is very heavy, there's a way to reduce it without disable important config like ECC and AES calulation (iniside the fsl_sss_ftr.h).

Thanks!

Hi @WorkerEmbedded ,

The nano package of MW should meet your requirements, please kindly refer to https://github.com/NXPPlugNTrust/nano-package/tree/master for details.

Have a great day,
Kan

Hi @WorkerEmbedded ,

The nano package doesn't support SSS APIs, so if your application is based on SSS APIs, you have to refine it with SE05X APIs instead.

Have a great day,
