ESFWU Maker Utility

Hi All,

I'm trying to flash a FW in a via I2C.

I've the correct HW setup (LPC EVK board and PN7642 EVK connected), and I can flash supplied firmwares.

My problem now is I cannot find the ESFWU Maker Utility (sw810311) mentioned to create suitable binaries myself.

Cannot find it in secure resources for PN7642.

Regards,

Hi Eduardo,

I found it under other name. HOST CRYPTO SCRIPTS.

I'm pending my NDA reactivation.

Thanks and Regards,
