LPC54S0xx Looking for base address of BOOT ROM RSA API

Hi,

I'm reading UM11060, Chapter 45.7 RSA API.

The boot ROM provides APIs to perform RSA2048 signature checking routines in
application code.

It goes on to show a table of functions with their offset.  Offset to where?  All I can find in the document is that Boot Rom is between 0x0300 0000 and 0x0300 FFFF. 

Applying the offsets to the start of Boot ROM yields a Hard fault for undefined instruction so that is clearly not the correct base address.  The document does mention that the ROM driver table is at 0x300 0200 and offsets are given for the USB, OTP, AES, RNG but not for the RSA API.

 

Where is a complete document of the ROM driver table for #LPC54S0xx ?

Hello @gtkp 

I have escalate this issue to DOC and SDK team, they still working on it.

And the latest reply is there is no RSA API in BOOT ROM code.

Hello @gtkp 

 

Try to  address 0x0300 023C ?

If still can not work, please tell me.

Hi Alice,

No the address 0x0300 023C also doesn't work.
