I despeately trying to get how to use :
- External RAM execution for a secure encrypted firmware on LPC43S57
- What is needed and how to write an ISP bootloader for secured device. Is a Secure Element needed ? How ?
At the end of UM10946 it's written :
Contact NXP Semiconductors for more information on third party software solutions for the LPC43S67 that utilize the A7001CM device.
How ?? There is no possibility to contact NXP Semiconductors ??
