[PATCH] console: Add option to keep it silent until env is loaded
by Harald Seiler 13 Jan '23

13 Jan '23

Add a config-option which forces the console to stay silent until the proper environment is loaded from flash. This is important when the default environment does not silence the console but no output must be printed when 'silent' is set in the flash environment. After the environment from flash is loaded, the console will be silenced/unsilenced depending on it. If PRE_CONSOLE_BUFFER is also used, the buffer will now be flushed if the console should not be silenced.

[PATCH 0/3] sunxi: remove CONFIG_MMC?_CD_PIN
by Andre Przywara 13 Jan '23

13 Jan '23

Since the dawn of time we had CONFIG_MMC?_CD_PIN defines for each Allwinner board, which held the name for the respective MMC card detect GPIO. These days we don't use that in U-Boot proper anymore (and rely on DT for that, instead), so it's just for the SPL loading. However the card detect is actually not needed there: - We continue loading from the same boot media that the BootROM booted us from, so when we get to load from MMC, there is surely a card in the slot. - The BROM already spoiled all efforts by unconditionally accessing the MMC bus, regardless of any card presence or not. We can't do more harm by doing the same. This series removes the code checking the CD pin, and also the definition from Kconfig and all defconfigs. On top there is a cleanup for the MMC driver, which explains the reason for still also implementing the legacy MMC interface. Please have a look and test!

[RESEND PATCH 0/2] rpi: Copy eth PHY address from fw DT to loaded DT
by Antoine Mazeas 09 Jan '23

09 Jan '23

Sjoerd Simons submitted the original patch (0001) to carry over some firmware-provided properties into the loaded device tree. This did not fix an issue with Raspberry Pi 400 rev 1.1 boards which would not be able to find the ethernet PHY device at the address specified by the kernel device tree. Patch 0002 expands on Sjoerd's design to also carry over the real ethernet PHY address, enabling the kernel to find and enable a working ethernet on pi 400 rev 1.1 boards.

[PATCH 0/3] sunxi: FEL boot fixes
by Andre Przywara 08 Jan '23

08 Jan '23

While investigating a FEL boot failure on the OrangePi Zero 2 board (with an H616 SoC), I stared at our FEL code and found some issues, which this series fixes. Unfortunately those didn't fix the H616 problem, but they are worth having anyway. For the records on the FEL failure: with certain H616 DRAM parameters, newer GCCs (starting with GCC 11, GCC 10 is fine) generate an SPL binary that doesn't properly return to the BootROM after the SPL code has finished. This does not occur on other H616 boards using different DRAM parameters. Staring at the disassemblies from the different compiler versions for a while didn't show anything obvious, the best theory so far is that it's due to a subtle timing issue in the DRAM initialisation code. Inserting a "udelay(0);" at the beginning of mctl_phy_read_calibration() seems to avoid the problem, but is obviously not a proper fix. I will keep looking. However the issues addressed in this series should be fixed, regardless. Cheers, Andre Andre Przywara (3): sunxi: armv8: fel: load only 32-bit values sunxi: h616: lower SPL stack address to avoid BROM data sunxi: fel: drop redundant "control register" save/restore arch/arm/cpu/armv7/sunxi/fel_utils.S | 4 ---- arch/arm/cpu/armv8/fel_utils.S | 8 ++++---- arch/arm/mach-sunxi/board.c | 1 - include/configs/sunxi-common.h | 2 +- 4 files changed, 5 insertions(+), 10 deletions(-) -- 2.25.1

linksys wrt1900acs v2 boot problem
by Dilyan Lazarov 07 Jan '23

Hi, I have a problem with my linksys wrt1900acs. My main question is this a hardware problem or software problem? Is it possible to address? I have started researching and have tried with "kwboot" under Windows VM - Ubuntu 20 - Linux but I have a problem with usb serial connection. I have tried several things but I understand that it isn't possible to start USB to Serial on a Windows VM. I will expect your response. Thank you in advance. All the best Dilyan I see the following Log from U-Boot with PuTTy under Windows 10: BootROM - 1.73 Booting from NAND flash General initialization - Version: 1.0.0 Detected Device ID 6820 High speed PHY - Version: 2.0 Init RD NAS topology Serdes Lane 3 is USB3 Serdes Lane 4 is SGMII board SerDes lanes topology details: | Lane # | Speed | Type | -------------------------------- | 0 | 06 | SATA0 | | 1 | 05 | PCIe0 | | 2 | 06 | SATA1 | | 3 | 05 | USB3 HOST1 | | 4 | 05 | PCIe1 | | 5 | 00 | SGMII2 | -------------------------------- :** Link is Gen1, check the EP capability PCIe, Idx 0: Link upgraded to Gen2 based on client cpabilities :** Link is Gen1, check the EP capability PCIe, Idx 1: remains Gen1 High speed PHY - Ended Successfully DDR3 Training Sequence - Ver TIP-1.26.0 mvSysEnvGetTopologyUpdateInfo: TWSI Read failed WL Supp: IF 0 busId 1 Failed !

kwboot : bug when board stops acking
by SC 06 Jan '23

06 Jan '23

Hi list, I think there's a bug in kwboot. I have a faulty board that stops acking xmodem frames after a certain number of packets and kwboot instead of exiting continues to send frames up to 100%. With the one second retry timer it's very long! More than 2 hours :-( The bug is in the kwboot_xm_sendblock() fonction : https://gitlab.denx.de/u-boot/u-boot/blob/master/tools/kwboot.c#L375 kwboot_tty_recv detects the timeout but the return value is based on the last character received (line 403) The variable c is not initialized so if it keeps the previous value which is ACK => rc=0 => infinite loop There are several ways to fix the bug: * Surround the "switch(c)" with a test: if ( !((rc == -1) && (errno == ETIMEDOUT)) ) { rc = -1; switch (c) { case ACK: rc = 0; break; case NAK: errno = EBADMSG; break; case CAN: errno = ECANCELED; break; default: errno = EPROTO; break; } } return rc; * In the case of a TIMEOUT set c to a specific value and add the case in the switch Do you agree with my diagnosis? What is the best solution to fix this bug? Should I provide a patch? Thank you, Stephane

[PATCH] rockchip: rk3328: Set VOP QoS to high priority
by Nicolas Frattaroli 05 Jan '23

05 Jan '23

The default priority for the quality of service for the video output results in unsightly glitches on the output whenever there is memory pressure on the system, which happens a lot. This sets the VOP QoS to high priority, which fixes this issue.
