What is pxa1826-cfg.tar.gz?

pxa1826-cfg.tar.gz is a file name that suggests it is a compressed archive. Let's break it down:

Example: Changing the System Console from UART1 to UART3

Edit uart_routing.cfg:

[UART_MUX]
CONSOLE_UART = 3   # was 1
BAUD_RATE = 115200

Then repack:

tar -czf pxa1826-cfg-new.tar.gz --owner=0 --group=0 pxa1826-cfg/

Important: After modifying, you must recalculate the CRC32 checksum if the bootloader expects it (stored in a header like board_config.bin.sig). Failure to do so will cause the boot process to fall back to safe defaults — or hang.

Inside the Tarball: Expected Directory Structure

Once you obtain a legitimate copy of pxa1826-cfg.tar.gz (often from a board support package or an archived manufacturer’s FTP server), decompressing it reveals a predictable structure for PXA development.

To extract the contents on any Linux or macOS system:

tar -xzvf pxa1826-cfg.tar.gz

After extraction, you will likely encounter a directory named pxa1826-cfg/ containing the following critical components:

6. Troubleshooting Common Errors

| Error Message | Likely Cause | Solution | |---------------|--------------|----------| | Bad magic number in pxa1826-cfg | Corrupted tarball or wrong endianness | Re-download; use tar -xzf, not gunzip -c \| tar x | | NAND partition overlap after config load | Modified partition map without updating offsets | Restore original nand_partition.map and recalc | | I2C device -19 (No such device) | GPIO/I2C mux conflict in gpio_mappings.ini | Check that I2C pins are not assigned as GPIO | | Kernel panic - not syncing: No init found | Rootfs partition erased by bad config | Reflash using vendor recovery tool (e.g., upgrade_tool) |

Where to Find pxa1826-cfg.tar.gz Today

Because the PXA1826 is considered a legacy part (no longer in active production by Marvell), official sources are scarce. However, legitimate sources include:

  1. Archived BSP CDs: Old board support packages from manufacturers like Toradex, Compulab, or Keith & Koep.
  2. Open Source Repositories: Some community-driven projects (Linux on Dell Axim, OpenZaurus) have mirrored these configuration files on GitHub or SourceForge. Search for "pxa1826 config" within those repos.
  3. Marvell Extranet (historical): If you have a legacy support contract, Marvell’s now-defoployed extranet once hosted these files.

Security Warning: Always verify the MD5 or SHA256 checksum of any pxa1826-cfg.tar.gz obtained from third-party sites, as configuration binaries can contain code that runs with Ring-0 (kernel) privileges.
