Tool/software: TI-RTOS
Hi,
AM5728 does not boot from 32 gByte SDCARD.
The same bootloader and app (TI-RTOS) work normally if copied to smaller card.
Are the any restrictions to size/type of SDCARD?
Thanks
Rasty
Rasty,
I got two new 16 GB and 32 GB SD cards and tested the HP USB Disk formatting and Linux create-sdcard.sh approach and both of them worked with the IDK AM572x setup.
Windows 7 setup with HP USB DIsk for SD card formatting:
1. HP USB Disk Storage Format Tool v2.0.6 Portable has to be used to format the SD card. This tool can be downloaded from this link.
2.Choose a SD card and a USB based or similar SD card reader/writer. Plug it to a Windows host system.
3. Run the HP USB Disk Storage Format Tool v2.0.6 Portable executable. The executable should automatically detect the SD card plugged via reader. Else point it to the new disk.
4. Choose FAT32 if the SD card size is greater that 4GB. Else FAT should be good to go.
5. Click on 'Start'.
After the formatting is complete, the card is ready to be populated with the files required.
This needs to be run as administrator takes a while to format and depends on the size of the SD card. Took about 20 mins on my Windows 10 PC.
6. Copy MLO and app file to the SD card that will be detected on windows as BOOT volume and insert the SD card in the idkAM572x and power up.
Linux SD formatting setup:
On Linux host where the SD is installed, follow the steps below:
sudo [SDK Install Path]/bin/create-sdcard.sh
[SDK Install Path]/processor_sdk_rtos_am57xx_<version>/prebuilt-sdcards/idkAM572x/sd_card_files/

Time taken to format : less than a minute and is easier for automation.
