Flashing .FFU file: write_sparse_image: Request would exceed partition size!

[nxpmichalminarcik]

Hi all,

I'm trying to flash .FFU file (Windows Full Flash Update) via UUU tool.

In the case of the .ffu file with Windows IoT Core (size 936 MB) everything is fine, but if I flash the .ffu file with Windows IoT Enterprise (size 6 900 MB) I get an error at the end: write_sparse_image: Request would exceed partition size!

I am currently testing with an i.MX 8M Mini board.

Do I need to change the partition size or work with .ffu files in another way?

I am attaching the logs.

Thanks in advance for your help
Michal

I am not sure. Can you shared your image?

Frank, I just shared an image with you. You should get an email where you can access the files. Thank you for your help.

Do you have ffu format spec? Your file dwDiskAccessMethod using 1 and 9, which is not supportted yet. I supposed 1 is from current, not sure what's 9 means.

typedef struct _DISK_LOCATION
{
uint32_t dwDiskAccessMethod;
uint32_t dwBlockIndex;
} FFU_DISK_LOCATION;
