Thanks Peter,

Now updated to a28 but still not really getting anywhere c.f. a25

  matherp said  The initialisation of the card is at 250KHz which should be OK for any card


What does this mean ? When I do a vanilla OPTION SDCARD GP15 then I get a default of 10 MHz:


> option list
OPTION COLOURCODE ON
OPTION CPUSPEED (KHz) 250000
OPTION SDCARD GP15, 10
OPTION SYSTEM SPI GP10,GP11,GP12


When I try to change the SDCARD option:


> option sdcard gp15,1
Error : SDcard already configured


Is this correct ?
Is there a way to OPTION RESET a single option ?
Or do I have to start from scratch ?

Even if I start from scratch with OPTION SDCARD GP15, 1 then I *sometimes* get the previously reported Error.

I am currently using a SanDisk Ultra 16GB:

I guess I can spring for another to circumvent this roadblock, though longterm I suspect you don't want it to be so "picky". Is this the card you are using ?
