If you want to create an Intel HEX image that is compatible to Analog Devices’ VisualDSP++
flash programmer, you need to type the following command:
8.5 Upgrading the U-Boot
If you want to replace the existing U‐Boot by a newer one, you can use U‐Boot itself for
upgrading. It is recommended to test the new U‐Boot image prior to programming it. In the
case of a non‐functional image, you would have to use a JTAG flash programmer or UART
boot (not supported by all Core Modules).
First, load the binary U‐Boot image (
loading files with U‐Boot are given in section 8.3.
Assuming that you used load address 0x1000000, type
at the U‐Boot prompt to execute the new U‐Boot. If it boots, the test was successful and you
can program the new image to flash memory. Reset the device, load
boot.ldr
After the programming process is finished, you can reset your device. The new U‐Boot is now
installed.
8.6 Booting U-Boot from UART
See the following web site for instructions how to boot U‐Boot from UART for processors
that support it (BF527, BF537, BF548):
8.7 Programming a uClinux image to flash memory
To program a uClinux image to flash memory, you must first transfer the uClinux and file
system images into the Core Module RAM. Please refer to section 8.3 for instructions.
You have several choices what to program into flash memory, here are two that are
commonly used:
