[U-Boot] Fwd: Marvell Armada XP u-boot from uart

---------- Forwarded message ---------- From: Konstantin Lezhnyev <konst.ru(a)gmail.com> Date: 2015-05-26 13:30 GMT+05:00 Subject: Re: [U-Boot] Marvell Armada XP u-boot from uart To: Stefan Roese <sr(a)denx.de> I'm sorry, the wording of my question was too short. I have already fulfilled the steps described in the article. But the article describes loading of the image from manufacturer - it is not my case. 1. I create a configuration for my board from maxbcm config. 2. Set `BOOT_FROM` parameter in board\my\kwbimage.cfg to `uart`. 3. Set DDR timings/settings. 4. Upload and execute image via uart. 5. Memory training ended successfully. But then I get the following messages in the terminal: | >>spl:board_init_r() | boot device - 8 | ... | SPI probe failed. Boot device 8 - constant `BOOT_DEVICE_SPI`. Function code returns this value looks like: | u32 spl_boot_device(void) | { | /* Right now only booting via SPI NOR flash is supported */ | return BOOT_DEVICE_SPI; | } And now I repeat my question: >Is it possible to load and boot Marvell Armada XP u-boot completely from uart without spi or nand flash? Regards, kon5t. 2015-05-23 13:08 GMT+05:00 Stefan Roese <sr(a)denx.de>: > On 22.05.2015 16:12, Peter Robinson wrote: > >> Is it possible to load and boot Marvell Armada XP u-boot completely from >>> uart without spi or nand flash? >>> I have custom board with MV78460 and clean flash memory. >>> >> >> You can use kwboot I believe. >> > > Correct. kwboot can be used to upload and execute a binary (compiled for > UART booting) via UART.

[U-Boot] [PATCH] tools/kwboot.c: Support UART fallback mode
by Kevin Smith 29 Mar '16

29 Mar '16

On some processors such as Armada 38x, if the hardware- configured boot mode fails, the CPU falls back to booting over UART. When this happens the chip prints a failure message, waits for the magic sequence and, when it is received, prints a "(boot)" message, then sends a NAK to start the transfer. This breaks the current kwboot behavior because the xmodem transfer only tries to read one character after the magic sequence, looking for the NAK. Instead it gets the "(boot)" text, and retries the magic sequence. The CPU thinks the repeated sequence is part of the packet, stops NAKing, and one side or another eventually times out. This patch adds support for a fallback mode which continues to scan for a NAK in the characters received after the sequence, printing out any non-NAK characters. This allows kwboot to skip the "(boot)" message, find the NAK, and start the transfer successfully.

[U-Boot] buildman for sandbox
by Joe Hershberger 13 Mar '16

13 Mar '16

Hi Simon, Is there a way to make buildman compile sandbox with a non-system tool chain? I've tried creating an alias from sandbox to i386 and removing the "root" entry. It then simply claims not to have a sandbox tool chain. Thanks, -Joe

[U-Boot] [PATCH v4] x86: baytrail: Configure FSP UPD from device tree
by Andrew Bradford 12 Mar '16

12 Mar '16

From: Andrew Bradford <andrew.bradford(a)kodakalaris.com> Allow for configuration of FSP UPD from the device tree which will override any settings which the FSP was built with itself. Modify the MinnowMax and BayleyBay boards to transfer sensible UPD settings from the Intel FSPv4 Gold release to the respective dts files, with the condition that the memory-down parameters for MinnowMax are also used. Signed-off-by: Andrew Bradford <andrew.bradford(a)kodakalaris.com> --- Changes from v3: - Fix small typographical issues (lowercase hex numbers, grammar, etc), no functional changes. Changes from v2: - Switch to using booleans in dts, where appropriate. - Add Bayley Bay dts modifications. - Clarify docs to show bool versus int properties. - Include enable-igt property from FSPv4. Changes from v1: - Use "-" rather than "_" in dt property names. - Use "Bay Trail" for the formal name of the Intel product family. - Use an "fsp," prefix for dt property names for clarity. - Fix minor code indentation issues. - Create a dt subnode for the memory-down-params. - Clarify documentation that dt overrides the FSP's config, so we don't use booleans. arch/x86/cpu/baytrail/fsp_configs.c | 167 +++++++++++++++++---- arch/x86/dts/bayleybay.dts | 40 +++++ arch/x86/dts/minnowmax.dts | 58 +++++++ .../misc/intel,baytrail-fsp.txt | 158 +++++++++++++++++++ include/fdtdec.h | 2 + lib/fdtdec.c | 2 + 6 files changed, 397 insertions(+), 30 deletions(-) create mode 100644 doc/device-tree-bindings/misc/intel,baytrail-fsp.txt diff --git a/arch/x86/cpu/baytrail/fsp_configs.c b/arch/x86/cpu/baytrail/fsp_configs.c index 86b6926..ba56ebb 100644 --- a/arch/x86/cpu/baytrail/fsp_configs.c +++ b/arch/x86/cpu/baytrail/fsp_configs.c @@ -1,14 +1,18 @@ /* * Copyright (C) 2013, Intel Corporation * Copyright (C) 2014, Bin Meng <bmeng.cn(a)gmail.com> + * Copyright (C) 2015, Kodak Alaris, Inc * * SPDX-License-Identifier: Intel */ #include <common.h> +#include <fdtdec.h> #include <asm/arch/fsp/azalia.h> #include <asm/fsp/fsp_support.h> +DECLARE_GLOBAL_DATA_PTR; + /* ALC262 Verb Table - 10EC0262 */ static const uint32_t verb_table_data13[] = { /* Pin Complex (NID 0x11) */ @@ -116,41 +120,144 @@ const struct pch_azalia_config azalia_config = { .reset_wait_timer_us = 300 }; +/** + * Override the FSP's UPD. + * If the device tree does not specify an integer setting, use the default + * provided in Intel's Baytrail_FSP_Gold4.tgz release FSP/BayleyBayFsp.bsf file. + */ void update_fsp_upd(struct upd_region *fsp_upd) { struct memory_down_data *mem; + const void *blob = gd->fdt_blob; + int node; - /* - * Configure everything here to avoid the poor hard-pressed user - * needing to run Intel's binary configuration tool.

[U-Boot] [PATCH v1 1/3] fastboot: OUT transaction length must be aligned to wMaxPacketSize
by Dileep Katta 11 Mar '16

11 Mar '16

OUT transactions must be aligned to wMaxPacketSize for each transfer, or else transfer will not complete successfully. This patch modifies rx_bytes_expected to return a transfer length that is aligned to wMaxPacketSize. Note that the value of ep->desc->wMaxPacketSize and ep->maxpacket may not be the same value, and it is the value of ep->desc->wMaxPacketSize that should be used for alignment.

[U-Boot] Weird error message on buildman
by Masahiro Yamada 07 Mar '16

07 Mar '16

Hi Simon, When I try to run Buildman against a branch named "test", it fails with a weird error message. $ git branch * master $ git checkout -b test master Switched to a new branch 'test' $ echo foo >> README $ git add README $ git commit -m foo [test f8f6569] foo 1 file changed, 1 insertion(+) $ tools/buildman/buildman -b test Branch 'test' not found $ git branch master * test Indeed, the branch "test" exists, but Buildman reports "Branch "test' not found". Could you check it out, please? Best Regards Masahiro Yamada
