Hi Stefan.
Apologies for the delay.
I will make this a priority to sort the issue out for you.

Hi Stefan.
I have thoroughly looked into this.
Unfortunately, the write functions are not supported, which is the reason they don't work correctly.
Many thanks for bringing this to our attention.
What I'm going to do is check all the functions, and if not supported I will add a tooltip with states its not supported.

Hi Martin
Thanks Martin
if the Sd-card works fast enough, I can do without some modes.
I guess these 3 points would already help me, to store data fast enough.
1. change to the next sector much faster
2. SPI clock should work and set to 50Mhz as an option
3. 4Bit mode working (there is no difference to 1Bit detectable)

Hi Martin
1. change to the next sector much faster
It would already help if this time was reduced by half. It's just a change to the next sector
reduce the "orange" time:

Hi Martin
I made a second version of my programme. I have used the normal SD card component and am testing it now with this
I have replaced all commands.
i guess it is slow but i can maybe write sectoren with 512byte like by the PIC32
The pins are like this:

config the Sd component:

add 2 pins and set to high

Hi Martin
I can write sectors with the old SD component, is this also possible with the 4bit SD component?
And can the 4Bit Sd component also work on an STM32?

Hi Martin
any news on the points yet?
1. change to the next sector much faster
2. SPI clock should work and set to 50Mhz as an option
3. 4Bit mode working (there is no difference to 1Bit detectable)
