Tool/software: Starterware
Hi,
We have SD card read/write issue in our customer's application using AM3352 + StarterWare_02_00_01_01+ SYS/BIOS.
The SD card driver from StarterWare is used as it is. The SD card read/write is not working in some particular SD cards
it seems working normal with other kinds of SD cards but according to the SD card maker's comment,
in both normal and abnormal SD cards the AM335x's SD card Driver's operation seems to be abnormal.
Please let us know if there are any known issues with regards to StarterWare SD card drivers or anything else to be taken care of.
Looking at the SD card commands below, the SD Card is intialized everytime it is accessed.
Q1:Could you please let us know in what condition does AM335x SD card driver sends reset command.
And every time CMD55 command is sent continuously after reset command CMD00.
Q2:We would like to know under which condition does the AM335x driver sends continous CMD55 command during reset.
