Hi,
with the use of the handy simple-fat32-fs I am trying to convince the
board mentioned above to
access the sdcard successfully.
The sdcard itsself has worked flawlessly on another board in conjunction
with zeptoforth.
The board utilzes the "bigger" version of the RP2350 (with 80 instead of
60 pins).
The sdcard uses SPI 1 on pin 30 (SCK), 31 (TX), 40 (RX) and 41 (CSn).
The code looks like this:
spi import |
<simple-fat32-fs> class-size buffer: my-fs | |
30 31 40 41 1 <simple-fat32-fs> my-fs init-object |
my-fs current-fs!
When loading this an endless loop is the result.
What did I wrong?
Cheers!

Would you perchance have links to the pinout and schematic for this board?
I took a look at the pinout for a board with the RP2350B and the above
*looks* correct in that you *could* use these GPIO's for SPI1 if you so
desired...

I figured out your problem ─ the SD Chip Select is GPIO43, not GPIO41,
according to the schematic. (Note that the SD Chip Select pin does not use
the SPI CS mechanism under zeptoforth but is controlled purely in software.)

Hi Travis,
ooooh! ...sorry.....thank you for finding this! :)
I fixed that in the code and it is now able to read the sdcard! Oh yeah!
A good start into
the weekend! :)
THANK YOU! :)
Cheers!
