NICE! will take a look, mind if i convert for other PICs or MCUs ? Skimmed over and seems too simple to be true but i havent tested it will test later on but cool!

Microchip has a sample of about the same thing

code is a good idea to develop. 18f sd card series.

mimimize and good repair the software would be nice if.

next rev blink led ;

strap LED error messages:

No Error : blink 1 and Led power

Error 1 : (blink 1 time and 2 seconds pause cycle) No entry point (->no software flashed)
Error 2 : (blink 2 time and 2 seconds pause cycle) SDCard init() error.
Error 3 : (blink 3 time and 2 seconds pause cycle) FAT32 error.
Error 4 : (blink 4 time and 2 seconds pause cycle) BIN File not found!
Error 5 : (blink 5 time and 2 seconds pause cycle) Bad data crc! (file corrupt)
Error 6 : (blink 6 time and 2 seconds pause cycle) Bad data size!
Error 7 : (blink 7 time and 2 seconds pause cycle) Write error (Pic flash error)

loader bug fix.

RB5 pin gnd and 1 second wait and sdcard load ok.
add timer wait code and blink sample
add test file portb 1/0
test ok.

next rev, code optimize and repair. add error code sample;
