I've got a nasty error:
Using STM32 - VS1053 (with SD card holder that I use): With all of my cards everything runs perfect. So I ordered for my mini serie project 10 pieces of:
Intenso Micro SDHC 32GB Class 10
Formatted with the SD tool
Now the magic:
After 1-10 minutes of playing MP3 files, everything freezes (I do not have the time until now for some debugging work). This occurs on every of the 10 card and every of the 10 player-PCBs and ONLY with this type. I used: 32GB Kingston, Sandisk various sizes, everything all right. But Intenso: crash after a few minutes.
Anybody did same symptoms with a specific card type?
I tried out: lowering SPI speed, different formats (FAT32, ExFat...) - same thing.
My next step would be:
Sketch with only SDfat library, reading the Mp3 Files step by step with all debugging option

Here are some benchmark results. Interesting point: the write speeds compared with Kingston. https://mcu.selfip.com/viewtopic.php?f=5&t=168&p=1428#p1428
So same class, same size, but a big difference!
Even the Class 4 of Intenso cards are slow at write speed (but much better as Class 10) - and: They are working even after an hour.
Some details/measurements of the Card Slot of the VS1053 module:
Voltage is totally stable at 3.3V
MISO, MOSI, CS, CLK are directly connected, without pull-up/pull-down resistors.
So I should be ok, the module is directly soldered on the PCB (no long cables or something).
I've already sent back the 10 pieces of cards and received 10 pieces of Kingston. Maybe someone with similar problems will read this archived / closed issue.
