There are two parts in my application- the bootloader part(without MQX OS)  +  the user application part(with MQX OS).

 

The SD card is used in my application. The new firmware is stored in the SD card.

 

The bootloader should get the new firmware from the SD card and copy it to the MCU.

 

If the bootloader does not support MQX system, is it possible to access the firmare in SD card by file address?

 

For example,the firmware is put in the address \Firmware\BasicUnit in the SD card.

 

The bootloader without MQX OS  want to get the firmware from the address in the SD card.

 

How should I do? Is there any example to do that?

 

The hardware is K64 and the OS is Freescale_MQX_4_1_TWRK64F120M.
