The conditions which change to Serial-Download-Mode

Dear All,

 

My customer are constructing the manufacturing process of the product using current i.MX6-Solo.

Their product is boot from parallel NOR-Flash via EIM interface.

 

When nothing is being written to NOR-flash (all contents 0xFF) in the Internal Boot Mode, We thought that it switches over boot from NOR-flash to Serial-Download-Mode.

However, their board does not switch over to Serial-Download-Mode. *PC does not detect USB-Device.

 

Once writing a program into NOR using Serial-Downloader, of course, the board is correctly boot from NOR-flash.

 

Doesn't i.MX6-Solo switch over to Serial-downloader, when reading 0xFF from NOR-Flash in boot?

Do my customer have to change Boot-Mode switch setting on the board in a manufacturing process?

 

Best Regards,

George
