Re: [U-Boot] u-boot-imx on Freescale MX28EVK
Hi Matthias, I a patch would be welcome. I only need USB and SPI flash for my application. And USB was easy to setup. Currently I am also jiggling around the SPI / SPI flash support. For USB, all you need to do is to configure it in and to copy Marek's clock setup in board_early_init_f for m28evk_config into your own config. Make sure you change SSP2 into SSP1, because the m28evk module uses a different SSP2 for it's second MMC controller, whereas the FreeScale mx28evk board uses SSP1. To store your environment in MMC, you still need to patch board/freescale/common/sdhc_boot.c to make sure it's stored at the correct offset. You can find this patch on this mailing list. Without it, saving your environment will overwrite the MBR/ptable and you board won't boot next time. But there is still the difference that I can download 2009.08 + imx-bootlets via USB (sb_loader). This does not work with the recent u-boot-imx repo and the generated u-boot.sb target. I don't know why that doesn't work, but I don't have any experience there. Early this year I rewrote the broken FreeScale scripts to create boot streams, so I know a little about the way it works, but I no longer use those since the U-Boot tools do such a good job. You can have the scripts though. Cheers, Robert. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Re: [U-Boot] u-boot-imx on Freescale MX28EVK
Hi Fabio, thanks for your details. Some of the discrete switches where messed up. Boot Mode was fine. So now it's working fine. Even the power button is not needed ;-) I still have to investigate a little to get USB recovery working. This does not work out of the box as with Freescale'S initial 2009.08 u-boot for this CPU.

Ok, good. m28evk has USB support as far as I know, so maybe you can look at it for reference. You did not really understand what I mean. I am not talking about using the USBs host/device from u-boot. The i.MX28 is capable to boot via USB. In this case the SOC's ROM implementes a HID device and you can use some tools on your PC (see previous posting) to download the code (boot jumper setting 0-0-0-0. I tried it with Freescale's sb_loader (Wind**s). This works fine when downloading a u-boot (imx28_ivt_uboot.sb) based on Freescale's 2009.08 source + imx-bootlets-src-10.12.01. But it does not work when using sb_loader with u-boot.sb build from the u-boot-imx repo. I can can imagine that the SPL code somehow breaks the internal download code.

Re: [U-Boot] u-boot-imx on Freescale MX28EVK
Hi Matthias, I have a fully functional U-Boot for the mx28evk board: - Both Ethernet ports work - Both MMC slots work - NAND works (if configure in, one MMC slot will be configured out, due to shared pins) - USB works - I2C works - Currently working on SPI It's basically an integration of u-boot-imx and Marek's work on m28evk_config in the mainline. I'm still working on making a posting-quality patch, but I'll be happy to help you out with a patch or a tar-ball, so feel free to drop me an email. Freescale's 2009.08 works too, but their script to get it on an sd-card is broken. I can get you a replacement for that one as well, but you'd better step up to a more recent version, because the MMC driver in the FreeScale version has a nasty bug in the MMC driver. This bug prevents you from loading files from a file system on an SD-Card. Robert. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
