Automatic Kickstart Selection

[Manger74]

Just a nice little idea...
If we could put a code for the kickstart in the HDF filename...

AGS_27_NanoMig.HDF -> AGS_27_NanoMig.K31.HDF

so when the HDD will be selected in the menu,
the code would be recognized and osd_kickstart
would be set to 2'b01 which triggers a kick switch and a reset...

would this happen in the FPGA-Companion or the top.sv?

Where would i have to place the function and where to call it?
Thanks!

name = "AGS_31_classic.K31.hdf"

call: osd_kickstart = sdc_detect_kickstart(name, osd_kickstart);

#include <string.h>
#include <stdint.h>
#include <strings.h> 

static uint8_t sdc_detect_kickstart(const char *name, uint8_t current) {
    if (!name) return current;

    // search for ".hdf" extension
    const char *hdf = strcasestr(name, ".hdf");
    if (!hdf || hdf < name + 4) return current;

    const char *pattern = hdf - 4;

    if      (strncasecmp(pattern, ".k13.", 5) == 0) return 0b00;
    else if (strncasecmp(pattern, ".k31.", 5) == 0) return 0b01;
    else if (strncasecmp(pattern, ".k3x.", 5) == 0) return 0b10;

    return current; // no match -> leave unchanged
}

IDE 1: will be drive b100? (nr.5)
and if we have osd_kickstart value, how can we send it to the core?

sdc.c

void sdc_mount_defaults(void) {
  sdc_debugf("Mounting all default images ...");

  // try to mount (default) images
  for(int drive=0;drive<MAX_DRIVES+MAX_IMAGES;drive++) {
    char *name = sdc_get_image_name(drive);
    sdc_debugf("Processing %s %d: %s",
	       (drive<MAX_DRIVES)?"drive":"image",
	       (drive<MAX_DRIVES)?drive:(drive-MAX_DRIVES),
	       name?name:"<no file>");
    
------> code placed here or function sdc_detect_kickstart called here?

    if(name) {
      // create a local copy as sdc_image_open frees its own copy
      char local_name[strlen(name)+1];
      strcpy(local_name, name);
      
      if(sdc_image_open(drive, local_name) != 0) {
	// open failed, also reset the path
	if(cwd[drive]) vPortFree(cwd[drive]);
	cwd[drive] = StrDup(CARD_MOUNTPOINT);
      }
    }
  }
}

Did you actually write and run that code?

[Manger74]

No, i've just prepared the code and i try to learn how the FPGA-Companion works...
is the code faulty?

#include <strings.h>
not available?

How about a fileselector to load alternative amiga.ini files followed by a reset?
Alternative config files could be easily created with a text editor.
The name of the .ini file could then show up in the menu after NanoMig:

NanoMig AGS 3.1
NanoMig OS3.3

How do you like the idea?

Naming convention: title.amiga.ini
