    Hello matusan,

    You are familiar with this thread right? There was an issue back in Processor SDK version 3 and your customer is using an old Processor SDK version. I suppose that because the latest Processor SDK versions doesn't fit into 4GB SD card. Maybe they are using the exact Processor SDK version 3 or older. First they need to update to the latest Processor SDK and check if that issue persists. Second, in my experience here in these threads here, here, here, here, here and here I got a feedback from some customers who faced issues with some SD cards, but these issues can be entity, batch, defective, counterfeit SD card or driver related issues, so that I cannot, recommend or not recommend you any SD card.

    Best regards,
    Kemal

    Hi,

    I typically used the Windows PC to format the SD card as FAT32, then directly copy files to it to boot. I didn't meet issue, I used different cards from 1GB, 4, 8, 16 and 32GB, they all from Sandisk. I knew some customer met the boot issue from various brand or size of SD cards, can you try the suggestion here: software-dl.ti.com/.../index_overview.html to see if it work for the failure card?
