[U-Boot] u-boot-x86 sf probe fail
by Hilbert Tu(杜睿哲_Pegatron) 14 Jun '16

14 Jun '16

Hi, I use Coreboot with u-boot-x86 as payload to bring-up my Intel Atom C2000 platform, but I cannot make my SPI flash(w25q128fv) to work. Actually the SPI was detected under coreboot with correct ID, but in u-boot “sf probe” command, it just always failed. After tracing and code dump, I found it was failed due to SPIS_FCERR in spi/ich.c spi_xfer function. I totally have no idea why this happened and how to proceed my bring-up. My u-boot-x86 is up-to-date version and the SPI use intel,ich9-spi compatible in my dts file. Following is my dm tree and there is spi-flash device => dm tree Class Probed Name ---------------------------------------- root [ + ] root_driver serial [ + ] |-- serial keyboard [ + ] |-- keyboard rtc [ ] |-- rtc timer [ + ] |-- tsc-timer pci [ + ] `-- pci pch [ + ] |-- pch@1f,0 irq [ + ] | |-- irq-router spi [ ] | `-- spi spi_flash [ ] | `-- spi-flash@0 pci_generic [ ] |-- pci_0:0.0 pci [ + ] |-- pci_0:1.0 pci_generic [ ] | `-- pci_1:0.0 pci [ + ] |-- pci_0:3.0 pci_generic [ ] |-- pci_0:e.0 pci_generic [ ] |-- pci_0:f.0 pci_generic [ ] |-- pci_0:13.0 usb [ ] |-- ehci_pci pci_generic [ ] |-- pci_0:17.0 pci_generic [ ] |-- pci_0:18.0 pci_generic [ ] `-- pci_0:1f.3 => Could you please give me some hint or tell me where I can reference?

[U-Boot] U-boot VESA driver Unsupported software interrupt #0x15
by vinoth eswaran 14 Jun '16

14 Jun '16

Hello Mr.Bin, In the latest U-boot-x86 version I am seeing some error messages when I enable the debug messages in the bios.c file. I am checking the VESA driver initialization and it seems that for a particular functional call it takes more time to process. realmode_call(addr + 0x0003, num_dev, 0xffff, 0x0000, 0xffff, 0x0, 0x0); -- it takes around 2 seconds. Do you have any idea how to optimize this function call or why it is taking that much time. I tried to enable the debug messages to understand what is happening and found that there are some software interrupts that are not supported [0.325805 0.002018] Real mode stub @600: 919 bytes [0.328829 0.003024] Calling Option ROM at c0000, pci device 0x10...

[U-Boot] [PATCH v5 0/2] common: usb_storage : Implement logic to calculate optimal
by Rajesh Bhagat 14 Jun '16

14 Jun '16

Performs code cleanup by making common function for usb_stor_read/write and implements the logic to calculate the optimal usb maximum trasfer blocks instead of sending USB_MAX_XFER_BLK blocks which is 65535 and 20 in case of EHCI and other USB protocols respectively.

[U-Boot] powerpc/85xx: usb: Limit controllers initialized by usb_init()
by Matthew Bright 14 Jun '16

14 Jun '16

Hi, I am looking for a way to limit which usb host interfaces are initiali- zed by usb_init() in order to skip unused interfaces. This is currently governed CONFIG_USB_MAX_CONTROLLER_COUNT, which is possible to redefine at the board level. However this doesn't cover more complex cases where a SoC has multiple host interfaces but a board using that SoC only uses a subset that is not necessarily contiguous. Does there currently exist a way to define such behavior, or should the functionality be added to usb_init() to support this? Thanks. Matthew Bright

[U-Boot] U-boot VESA driver Initialization
by vinoth eswaran 14 Jun '16

14 Jun '16

Hello Mr.Bin, Hello Mr.George McCollister, I am working on an embedded project to optimize Linux boot up time. I have a camera application, which I need to run as fast as possible after powering up the board. For this currently I am analyzing how can I optimize the U-boot. As of now, u-boot takes around 3 to 4 seconds and most of the time is spent, around 2 secs in initializing the VESA display. I have analyzed the sequence of VESA initialization flow and I have identified that realmode_call under the function bios_run_on_x86() takes more time -- around 1.7 Sec, realmode_call(addr + 0x0003, num_dev, 0xffff, 0x0000, 0xffff, 0x0, 0x0); Do you have any idea why this is happening? I tried removing the VIDEO configuration from u-boot, though the boot up is fast , the i915 driver from Linux is reporting an error -- 'i915 0000:00:02.0: Invalid ROM contents' I understand that the Linux kernel expects the underlying boot loader to setup some initialization which is missing in this case. Do you know any methods by which I can speed up the video driver initialization phase in u-boot. Please note that I don't need video support during u-boot phase,I am not going to use any splash images. Mit Freundlichen Grüßen VinothKumar +49 1798909072

Hello U-Boot developers, In Minnowmax board, I am trying to enable the debug messages of u-boot. When I try to enable the debug messages either through adding -DDEBUG flag in config.mk or by adding #define DEBUG in include/common.h file , I am getting the following error messages. U-Boot image overlaps with region './board/intel/minnowmax/vga.bin' U-Boot finishes at offset 798820, file starts at 790000 make: *** [u-boot.rom] Error 1 Any help on this is very much apreciated. Thanks & Regards, Vinothkumar
