Flexbus CS3 K63

aussiemate — Mon, 15 Feb 2016 00:20:33 GMT

I currently have an issue getting the Chip Select 3(CS3) Port C19 working with the flexbus on the K63 micro.

I already use CS0 and CS2 to access a PSRAM and LCD respectively.

I have setup the CS3 the same as the CS2 and I don't see the CS3 line change.

In the Manual it states that CSCR[AA] bit must also be set, which I believe I have.

I have the following configuration.

PORTC->PCR[19] = PORT_PCR_MUX(5); //CS_3

FB->CS[3].CSAR = 0x80000000

FB->CS[3].CSMR = FB_CSMR_V_MASK;

FB->CS[3].CSCR = FB_CSCR_AA_MASK;

FB->CS[3].CSCR |= (FB_CSCR_PS(2)|FB_CSCR_WS(0x0e));

FB->CSPMCR = (FB_CSPMCR_GROUP4(1)|FB_CSPMCR_GROUP5(1));

Has anyone else had issues getting the CS3 on flexbus working.

Am I totally missing something?

Any Help greatly appreciated.

OK, My mistake the CS3 is working... The settings mentioned above are ok.

Please don't ask why I thought it wasn't, it will only make me feel bad. ( has to do with not actually monitoring the CS3 line)...
