K60 rev 1.x rev2.x unique firmware

nickbridge — Fri, 01 Aug 2014 16:00:42 GMT

Dear all,

using K60 microcontrollers, can I distinguish from firmware which silicon version I'm using?

Is there a register that reading it tells me which silicon version has that microcontroller?

If it's possible I would write only one firmware that loads different registers when I'm using rev1.x silicon and when I'm using rev2.x silicon.

Thanks in advance,

Nicola

Certainly! For instance:

if( (SIM_SDID & SIM_SDID_REVID_MASK) == 0)	//For Rev 1.0 silicon, must disable all Flash caching & Speculation
{
FMC_PFB0CR	&= ~0x1FUL;	//Clear these bits for errata e2647 & e2644
FMC_PFB1CR	&= ~0x1FUL;
}

Or, more generally:

switch((SIM_SDID & SIM_SDID_REVID(0xF))>>SIM_SDID_REVID_SHIFT)

{

case 0x0:

printf("Silicon rev 1.0\n");

break;

case 0x1:

printf("Silicon rev 1.1\n");

break;

case 0x2:

printf("Silicon rev 1.2\n");

break;

case 0x3:

printf("Silicon rev 1.4\n");

break;

case 0x7:

printf("Silicon rev 1.8\n");

break;

case 0xA:

printf("Silicon rev 2.2\n");

break;

case 0xC:

printf("Silicon rev 2.4\n");

break;
