Now you can connect to PEEDI with Telnet. The RedBoot prompt appears. Type the
command
to start the update process (assuming that the file “firmware.bin” in your TFTP directory
contains the new firmware).
6.2.4 Debugging the uClinux kernel
Follow the instructions in the Readme file on how to compile the kernel. After the uClinux
image is programmed into flash memory, start GDB with the command
Note that you have to take the “vmlinux” file from the “linux‐2.6.x/” directory because it is
the only one that contains debugging symbols for GDB.
Example:
6.2.5 Debugging uClinux applications
Because of some bugs in bfin‐uclinux‐gdb as mentioned in the Readme file, it is
recommended to use gdbserver for debugging uClinux applications as described at
http://docs.blackfin.uclinux.org/doku.php?id=debuggers.
6.3 ICEbear JTAG
The ICEbear adapter from Section5 (http://www.section5.ch) in conjunction with libbfemu,
gdbproxy and the GNU tool chain (binutils, gdb, gcc) is a cost effective development tool for
Blackfin hardware platforms. Based on a USB 2.0 (1.1 compatible) connection to the host PC,
it 'outsources' all the JTAG signal generation to a dedicated JTAG controller, yielding
improved timing and signal integrity compared to a classic parallel port connector.
It mainly supports:
Supported CPUs (in brackets: CPU types that are compatible, but not tested):
Blackfin uClinux User Guide
• U‐Boot and kernel boot in the serial console window as usual.
• Hit Ctrl+C for halting the processor.
• Create a sample breakpoint and continue
• Now type „ls“ on the serial console running uClinux. The breakpoint will be hit.
• Fast flash programming (~20 sec. per MB or 50 kB/s under MS Windows)
• Loading and debugging of executables
• Automated system testing
• ADSP‐BF527 in 1.3 release
• ADSP‐BF533, BF531, (BF532) , ADSP‐BF534
• ADSP‐BF536, BF537, BF539, BF539F4 (BF538)
