Using OpenOCD with a JTAG adapter (e.g., Flyswatter or J-Link):
openocd -f interface/jlink.cfg -f target/pxa1826.cfg
> load_image pxa1826_cfg.bin 0x5c000000
> resume 0x5c000000
This loads the configuration into the PXA’s internal SRAM and executes it. pxa1826-cfg.tar.gz
The name itself is a combination of three distinct parts: Using OpenOCD with a JTAG adapter (e
In essence, pxa1826-cfg.tar.gz is a compressed configuration archive containing the board-specific initialization scripts and binary blobs necessary to bring a PXA1826 processor from a cold reset to a state where it can load a bootloader (like U-Boot or RedBoot). This loads the configuration into the PXA’s internal
Even with the correct pxa1826-cfg.tar.gz, things can go wrong. Here are the top three issues developers encounter:
You don't just "run" this file. Instead, the configuration data inside is consumed by tools like JTAG debuggers (e.g., Lauterbach Trace32, OpenOCD) or by the PXA’s internal boot ROM.
Here is a standard workflow for using the contents of pxa1826-cfg.tar.gz:
