Source code for OTP AES custom loader

Post by mmar »

For security XMOS use OTP and keys.
Customized flash loader howto dont say how create customized OTP.

I have code with start sequence write to serial latch register external, for hw setup.
When code is used unecrypted an started from flash, delay of write to latch is small, but
encrypted load and start same code AES is delayed very long unusable for me.

I need move latch write operation to OTP (or custom flashloader for speedup)

Have anybody info about this?

The OTP library is not published by XMOS and this cannot be done unless you modify the boot loader section and there is really no way of doing this at the moment.
