Hi Detlev, thanks for the help. I have tried CONFIG_CMD_CACHE but this doesn't work, because dcache_enable() is not implemented for PXA.

I fear this is not as easy as flipping a bit in a register. Depending on the platform caches tend to be tied to the MMU, so enabling the caches require setting up correct data structures for the MMU to work. That's the non-trivial work. Apart from that, there is CONFIG_CMD_CACHE which builds common/cmd_cache.c. I see that at least two PXA250 platforms enable this, so maybe simply try that? Moreover, a quick qoogle showed that the (non-mainline) Gumstix verdex (PXA270) U-Boot port has a dcache command: http://docwiki.gumstix.org/index.php/U-Boot Maybe you can reap the code from their repository.

Very likely the disabled instruction and data caches. Not that I know for sure, but I'm pretty confident that either both or at least the data cache is not enabled per default.

Re: [U-Boot] Starting compressed win CE kernel
Dear Jean-Christophe PLAGNIOL-VILLARD, I tried to use the unzip command of U-Boot, to unzip a Win CE Kernel. If I have a file size of roughly 10MB it takes 1 minute to uncompress the kernel. This is too long for my application. I use an PXA270 CPU with 64MB SDRAM. How can I make the unzip command faster? Description of my U-Boot application: At the moment I start Win CE from the flash memory in roughly 25 seconds. But the image takes much space on the flash, because I haven't compressed it at the moment. So I will use the zip functionality of U-boot to save space on flash memory. But this is only reasonable, if I can start the OS in roughly the same time as before.

If bootm use the same code like the unzip command, then it couldn't be faster. But I have compressed a nk.bin Windows Image file with GZIP. Then I uncompressed the 10MB File with U-Boot. It takes roughly 1 minute. And this is to much I think. What could I do to reduce the uncompression time? My hardware works with an PXA270 CPU.

[U-Boot] Starting compressed win CE kernel
Hello, I use U-Boot for starting Windows CE. At the moment I take the nk.bin File and start it with the U-Boot patch of Ryan Chen. Now I will compress the nk.bin file, because in addition to that it takes much less space in the Flash memory. I have tried it with the unzip command, but it takes too much time. Can I use another compression tool from u-boot. I think a compressed linux kernel can be started with bootm. So can I use maybe only the compression tool of the bootm command? If so, how can I do this? Thanks, Andreas ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
