Even with the correct pxa1826-cfg.tar.gz, things can go wrong. Here are the top three issues developers encounter:
Many PXA1826 systems boot from NAND flash. This subdirectory contains the bad block markers and the NAND controller timing parameters critical for the internal boot ROM to load the first-stage bootloader. pxa1826-cfg.tar.gz
Some files in the tarball may be C headers (.h) that need to be compiled into a binary configuration blob. A Makefile is often included. Run: Even with the correct pxa1826-cfg
make pxa1826_cfg.bin
file pxa1826-cfg.tar.gz
# Expected output: gzip compressed data, from Unix, original size modulo 2^32 ...
The name itself is a combination of three distinct parts: file pxa1826-cfg
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).
