Serout2 PORTC.6, 84, ["Init: ", Dec FAT_error, " ", Dec SDC_status, " ", Dec SDC_response, $d, $a]

Hi, Sorry I spoke too soon, this is what I get when I'm trying to transfer to another port/pins "’nit: 6 2 0"

[mackrackit]

From the SDFS file, the 6 and 2 from the generated errors.

CE_INIT_ERROR Con 6 ' An initialization error has occured
sdcCardNotInitFailure Con 2

From section 10.3 18F4550 data sheet.

On a Power-on Reset, these pins, except
RC4 and RC5, are configured as digital
inputs. To use pins RC4 and RC5 as digi-
tal inputs, the USB module must be dis-
abled (UCON<3> = 0) and the on-chip
USB transceiver must be disabled
(UCFG<3> = 1).

And do you have the Capture / Compare turned off for PORTC?

Thanks for helping me out mackrackit..but I'm still having trouble running the following(I'm really sure if I'm getting the settings correctly).

Include "modedefs.bas"

Kindly check my hardware Connections

SCK ------- RC3
MISO -------RC4
I'm not having a display in the terminal to identify the error produced, What do you think I'm missing?

Thanks in advance,

SDC_UseHardSPI = TRUE ' Use hardware SSP port for SPI.

Should be FALSE

[tacbanon]

That was it Dave, thank you for sharing your time...But I have another question, can I still make USB CDC with the setup we modified?regards,tacbanon

[mackrackit]

RC4 and RC5 are the USB pins.
