File System loaded from 4GB SD-Card

Hi Francesco,

My micro SD card is 4GB and it works fine with the DM816x/AM389x EVM. I made it with the mksdboot.sh script described here:

ti-ezsdk_dm816x-evm_5_05_02_00/docs/DM816x_EZ_Software_Developers_Guide.pdf

 6.7 How to create an SD card

host $ sudo ${EZSDK}/bin/mksdboot.sh --device /dev/sdb --sdk ${EZSDK}

Hi Pavel,

I'm working with EZSDK 5.05.01.04. Something has changed in the release you use (5.05.02.00)?

Regards

Francesco,

Regarding this script, nothing has been changed between these two release versions. The 4GB SD card should work fine with 5.05.01.04 script also.

Hi Pavel,

thank you. My 4GB SD card is a micro-sd, whereas the 8GB is a standard sd-card (of course, in order to use it I replaced the SD slot in my board). Could this be the difference? Have you experienced some troubles with micro-sd? I can say that, once the operative system is booted (to boot I need to load the file system from a NFS server), I can see the micro SD and all its content.

Regards

Francesco,

I have only 4GB micro SD cards, and I do not have any problems with these.

In fact I have verified that is true: my 4GB SD-card doesn't work

Could you please check if this non-working 4GB SD card can be mounted successful on the Ubuntu Desktop PC? And do you have two partitions: /media/BOOT and /media/ROOTFS? The BOOT partition should contain the MLO, u-boot.bin and uImage file (and few others), while the ROOTFS should contain your root file system. At which stage of the booting process, the flow crash/freeze/hang/stop?

Pavel
