Bääääär Posted March 22, 2011 Report Posted March 22, 2011 Hallo Community! I've been messing around with the SD-Card feature of MIOS32. I soldered a quick and dirty connector for SD Cards and plugged it into J16 on my core32. However, it seems not to be right how I did it. Some details: I "jumped" the jumper next to J16 to 3.3V. I uploaded the sdcard test app from the mios32 svn (compiled with some warnings, but seemed to be ok). On startup it promts me to press a button. Doing so, it answers[19935.257] Abort on connect, error code: 0 Meaning the card is not available. I double-checked the wires and connector, but it looks fine. The card is a sandisk 2GB card, formatted to 512B-clusters using win7. Anyone an idea? Thank you, Bääääär
gomiboy99 Posted March 22, 2011 Report Posted March 22, 2011 Did you take out the SIL resistor R30 on J16, this not required when using the SD card. Took me a while to figure that one out. Tim.
Bääääär Posted March 22, 2011 Author Report Posted March 22, 2011 OMG, yes, that's it! Thank you so much :hug: Maybe TK could add a short hint to ucapps.de, so other people having trouble can see why
gomiboy99 Posted March 22, 2011 Report Posted March 22, 2011 It is shown quite clearly here : http://ucapps.de/midibox_seq/mbseq_v4_interconnections.pdf but then if you are not building the mbseq it is easily missed. Glad that solved your problem. Tim
TK. Posted March 22, 2011 Report Posted March 22, 2011 I must say that I haven't expected that R30 could disturb serial transfers to the SD Card - I will add a comment! Best Regards, Thorsten.
