I can change cboot boot logo on TX2 devkit with following ticket method. But my carrier board can’t show anything when in cboot start process. I can see HDMI initialization is failed from start log, but when it start in kernel, HDMI display is ok. How to enable HDMI in cboot with my carrier board to…

guohoujin2006, Please apply these two patches to your cboot. diff --git a/drivers/eeprom/tegrabl_eeprom.c b/drivers/eeprom/tegrabl_eeprom.c index a2d5284..400be17 100644 --- a/drivers/eeprom/tegrabl_eeprom.c +++ b/drivers/eeprom/tegrabl_eeprom.c @@ -1,5 +1,5 @@ /* - * Copyright (c) 2015-2017, NVI…

Hi WayneWWW: Thanks for you reply, I download cboot source code from following website, and I meet a error when I compile it. Jetson Linux Jetson Linux 35.1 is a production release and replaces Jetson LInux 34.1.1/34.1 which were meant for development only. Jetson Linux 35.1 includes L…

I resolve the compiling error. I find in cboot, HDMI not display may caused by “vdd-hdmi” not enabled. I want to know how to configure bootloader dtb and compile it, thanks!

Is there a git repo tag available for this? I’m thinking of source_sync.sh instead of: https://developer.nvidia.com/embedded/linux-tegra

WRT the compiler errors, we only spec the 4.8.5 gcc & tools that we provide in devtools for CBoot source build right now (see CBoot_Standalone_Readme.txt in the source archive), as that’s the same toolset we use internally. Using a newer gcc will generate warnings/errors as it encounters code that n…

The cboot source code I downloaded doesn’t have git repo tag, I will download Jetpack 3.2.1 and use source_sync.sh instead of https://developer.nvidia.com/embedded/linux-tegra . Please check the attached picture, it show my carrier board cboot log compared with TX2 devkit. If kernel DTB and the boot…

I have fixed this problem, I modify vdd-hdmi regulator gpio in tegrabl_fixed_regulator.c, then this problem is resolved. BTW, I can’t use source_sync.sh to download cboot source code. /* FIXME - To obtain GPIO chip_id based on regulator name */ if (strncmp((const char *)temp_name, "vdd-hdmi", si…

Hi WayneWWW: This patch is ok for this problem, thanks very much!

guohoujin2006, Thanks. The patches would be included in next release.

I find a bug about this cboot source code: If I change internal EEPROM value of ethernet/WIFI mac area and also update the CRC checksum of the EEPROM, after reboot, the ethernet/WIFI mac can’t be updated. I got another cboot.bin from NV internal supporter before to fix this bug, but this bug recurrent now. It seems, the cboot source code not fix this bug.
