* [U-Boot] U-Boot on nyan-big via legacy boot [not found] <54807914.7020703@codethink.co.uk> @ 2014-12-04 15:23 ` SimonH 2014-12-04 15:53 ` Simon Glass 0 siblings, 1 reply; 4+ messages in thread From: SimonH @ 2014-12-04 15:23 UTC (permalink / raw) To: u-boot Hi Simon, I'm trying to boot a Linux distribution of choice on the Acer CB5-311-T9XM (nyan-big). I applied your patches from last Wednesday (v4, without the display driver) and flashed the patched uboot to the RW_LEGACY section after running this script with some objcopies (https://chromium.googlesource.com/chromiumos/overlays/chromiumos-overlay/+/master/sys-boot/chromeos-bootimage/files/build_cb_legacy_uboot.sh). Afterwards I jumped into the legacy section with Ctrl+L. Unfortunately it just resets the board after some seconds. The reset cause is: "reset-pin" and "hard". Find the EC UART output at the bottom. Using the norrin.board pinmux instead of nyan-big.board didn't change the behaviour (GPIO PI5). Do you have an idea what I'm doing wrong?

From my investigation, Coreboot is issuing this reboot command, because the Coreboot payload (which in my case is U-Boot) for some reason isn't valid. With CONFIG_PANIC_HANG defined there is no UART output from the EC at all. Is a prepended SPL needed before the U-Boot+DTB payload? When flashing U-Boot from the Chromium OS branch it gives some UART output but freezes because SPI and MMC driver are not working properly ("emerge-nyan chromeos-u-boot").

Yes, and I'm not sure of the state in the branch. Which branch? See u-boot-dm/nyan-working for an upstream version. It boots (at least from USB A-A) and the display comes up. To do: EC, keyboard, USB, maybe other things. Regards, Simon ^ permalink raw reply [flat|nested] 4+ messages in thread
