[U-Boot] [ppc] qemu-ppce500 howto
by Alon Bar-Lev 25 May '14

25 May '14

Hi, Trying to run the qemu-ppce500 within qemu. I am using -bios u-boot.bin and no luck, I get live signal. I am using latest u-boot master and qemu master. Command: $ ./qemu-system-ppc -M ppce500 -nographic -bios u-boot.bin Tried to load u-boot as well, same. Are there any patches pending or any tweak that should be done? Is there any way to provide more information? I tried: $ ./qemu-system-ppc -M ppce500 -nographic -M ppce500 -m 256 -s -S $ gdb (gdb) target remote :1234 Remote debugging using :1234 warning: Can not parse XML target description; XML support was disabled at compile time 0x00000000 in ?? () (gdb) load u-boot Loading section .bootpg, size 0x2f4 lma 0xf00000 Load failed How can I inject the firmware using gdb? Thanks! Alon Bar-Lev

Is it possible to load a bare-metal standalone application by using uboot, and let the standalone app load a kernel and FS, could you please propose a hint on how to it? Many thanks. -- View this message in context: http://u-boot.10912.n7.nabble.com/Uboot-standalone-kernel-tp180527.html Sent from the U-Boot mailing list archive at Nabble.com.

[U-Boot] [RESEND][PATCH] gpio: spear_gpio: Fix gpio_set_value() implementation
by Axel Lin 25 May '14

25 May '14

In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

[U-Boot] spi_flash_probe returns zero idcodes and hangs
by Amit Mahadik 24 May '14

24 May '14

Hello All, I am using a custom ARM based development board running u-boot from PNOR memory. However, it does not have support for the Micron SPI flash memory (N25Q064A). I have added support for the micron memory in drivers/mtd/spi/stmicro.c file and included the flag CONFIG_SPI_FLASH_STMICRO in the config file and recompiled the u-boot source source. Then, ran it directly through RAM memory. The new u-boot ran from RAM. Now when I run sf probe 0 command I get the following output Got Idcodes 000000: 00 00 00 00 and the code hangs after this. Please help me regarding this issue. Regards, Amit.
