Download starts. The messages Transfer Completed, <filename> Received and <number>

Bytes are printed upon completion.

Note:

The default external SRAM address used to store the downloaded images is 0x62000000. The

image size is automatically saved as a global variable after image transfer is completed.

The uClinux binary has been downloaded to SRAM. Go on to the next section,

Program the image to external Flash

Now, the Flash programming module is used to program the image that you have downloaded to the

SRAM into the external Flash memory.

To do this:

1

Press 2 to select the menu item Program External Flash. The bootloader will prompt you for

an offset address of the external flash to be programmed to.

2

Enter the number for the offset address (You can type A to cancel this operation). If the number

that you enter is invalid, the bootloader will prompt you for a new entry.

The following data formats are all valid for inputting numbers:

Note:

The bootloader uses 0x62000000 as the source address by default.

3

If the image size hasn’t already been saved, the bootloader will prompt you to enter the size,

otherwise the previously saved value is used (See note in

Section 3.4). It you receive this

prompt, enter the number corresponding to the size (You can type A to cancel this operation). If

the number that you enter is invalid, the bootloader will prompt you for a new entry.

4

The bootloader checks the address range and performs the erase and program operations

automatically (

Figure 8).
