Trying to get RL-FlashFS working on LPC2300

Perdrix over 2 years ago

I'm building some code to read the SD Card on an MCB2300. I'm using the RL-FlashFS library.

I have configured CCLK to 48MHZ and PCLK_MCI to CCLK, and changed the #defines in MCI_LPC23xx.c to read:

#define __MCLK    48000000
#define __CPUCLK  48000000

My code to initialise the card reads:

	uint32_t retv = finit(NULL);

The SD LED on the MCB2300 board comes on when the call is made and then there's a *long* pause and eventually the function returns a value of 2.

I'm using 4.74 of the library and uVision 5

Help please, I am totally baffled.

Thanks, David

I ran a manual flash of the build and was able to get into the debugger.

I had changed this code to let me debug the finit call:

static void init_card (void) {
  U32 retv = finit (NULL);
        char buffer[16] = {0};
    
    if (0== retv) return;
    else
    {
        sprintf(buffer, "%d", retv);
    }
}

When I debugged through that I got retv of 2 as previously.

For the avoidance of doubt I am trying to build/use the sample from directory:

C:\Keil_v5\ARM\Boards\Keil\MCB2300\RL\FlashFS\SD_File

that was installed by MDK79525. This has version V4.51 of MCI_LPC23xx.c and File_Config.c as distinct from the version in the downloadable sample which is V3.21.

Of course the V3.21 code won't compile:
