[U-Boot] [PATCH/RFC] mx28: print bootmode with cpuinfo
by Matthias Fuchs 24 Jan '12

24 Jan '12

Hi, while playing around with the mx28evk and differnet bootmedia I found it helpful to see the current bootmode without running to the board and checking it's switches. Also some other CPU (e.g. 440 PowerPCs) print some kind of bootstrap configuration during startup. The patch probably needs some little cleanup. But the main issue might be the way how it passes the information from SPL to 2nd stage. I am note sure if those scratch registers are somehow holy :-) BTW, I still did not figure out why current mx28evk u-boot cannot be bootet via USB download while MMC and SPI are working ... Matthias So here comes V1: This patch add support for printing the currently selected bootmode within print_cpuinfo() for MX28 boards. The bootmode is read from the CPU's strapping balls before they are setup for thier later function (e.g. become an output or are used by the LCD controller). Reading the pins is done from SPL stage and the information is passed in the SCRATCH1+2 registers together with the memory size.

[U-Boot] [PATCH V2 0/6] mxc_spi refactoring (for mx6q and mx6qsabrelite)
by Eric Nelson 24 Jan '12

24 Jan '12

This patch set refactors mxc_spi as described in http://lists.denx.de/pipermail/u-boot/2010-March/068791.html and requested in http://lists.denx.de/pipermail/u-boot/2012-January/116023.html in order to add support for the MX6Q in general and the mx6qsabrelite specifically. Patch 1 simply moves the conditional parts of mxc_spi.c into the respective CPU-specific imx-regs.h files. Patch 2 adds general support for SPI to the i.MX6. Patch 3 adds support to the mx6qsabrelite board Patch 4 modifies the 'sf' command to allow a default chip-select to be specified by board headers as is done on efika et al. This allows a bare 'sf' probe command: U-Boot> sf probe instead of the more cumbersome usage when a GPIO is tacked onto the chip-select. Otherwise, this command-line would be needed to specify GP3:19 on SabreLite: U-Boot> sf probe 0x5300 Patch 5 adds default chip-select values for mx6qsabrelite platform. Patch 6 adds reference macros for use in storing the environment in serial flash to match the use on Freescale's U-Boot release This patch set has been compiled against the following configurations, but only tested on mx6qsabrelite: mx6qsabrelite mx51evk mx31pdk mx35pdk

[U-Boot] USBTTY for CONFIG_USB_GADGET
by Michael Schwartz 24 Jan '12

24 Jan '12

Hi, Can new UDCs be written for CONFIG_USB_DEVICE or is that deprecated in favour of CONFIG_USB_GADGET? If that is the case and CONFIG_USB_DEVICE is deprecated, if I want to get USBTTY enabled for a currently unsupported UDC I would need to port USBTTY to CONFIG_USB_GADGET; is there interest in that effort or is there some alternative? Thanks, Michael Schwartz

[U-Boot] u-boot script "test"
by Sridhar Addagada 24 Jan '12

24 Jan '12

What is the behavior of test command when the variable is not present in the uboot env set x if test $x = 1; then echo "Yes"; else echo "No"; fi in the above case I get Yes echoed back. Is there any way to test the presence of a variable in uboot script? Thanks Sridhar

[U-Boot] [PATCH] tools/env: allow overwrite of ethaddr on default
by Grant Erickson 23 Jan '12

23 Jan '12

This patch allows the U-Boot user space companion utility, fw_setenv, to overwrite the 'ethaddr' key/value pair if the current value is set to a per-board-configured default. This change allows 'fw_setenv' to match the behavior of 'setenv' / 'env set' on the U-Boot command line.

Re: [U-Boot] About mtest on boot

isn't U-boot's address given by the relocadrr variable? If it is so, it is already at the end of ram and I'm giving a smaller end address to the ram - I'm getting relocaddr 0x07fcd000 and using this minus 0x01000 as ending position... Érico V.
