microcontroller – Data misaligned when writing to SDHC card over SPI – Stack Overflow
Hitachi HF13 introduced in ; New Mold. I was out of sync, so that each time I was writing an SPI byte, waiting for transmission and then reading from the buffer, I was actually getting the previous result and not the current one.
I just had the exact same problem, which turned out not to be a problem with the SD card, but with my SPI interfacing. Learn how to harness the compute power of the Altivec Engine and leverage libraries developed by Mentor Graphics. The particular chip I was using Freescale KL03 will retain the current received byte in the data buffer until you read it, even after you have started sending the next one.

SDHC controller (SBC-i.MX51)
The data itself is misaligned one to the left. Ferescale summary, ensure that you are sending the 7E immediately after the 00 response to your write command. And I’m able to read and write data to it properly. Upon dumping the raw blocks on the card. Electrostatic discharge voltage, human body model.
