器件型号：TDA4VP-Q1

工具与软件：

您好！

我有一个定制的 j784s4 GP 板、我要为其创建：tiboot3.bin、tispl.bin_unsigned、u-boot.img_unsigned。
我根据指令编译了 tisdk-tinlinux-image 映像
我位于 Yocto-build/build/deploy-ti/images/j784s4-evm 文件夹下：tiboot3-j784s4-gp-evm 、 tispl.bin、u-boot.img
如何也编译 tispl.bin_unsigned、u-boot.img_unsigned 文件？

谢谢！
Rachel

您能告诉我们为什么需要 tispl.bin_unsigned 和 u-boot.img_unsigned 文件吗？您是否无法使用生成的 tispl.bin 和 u-boot.img？

谢谢。

您好！

当我尝试加载 tispl.bin 文件时、TDA 似乎卡住了、
我看不出来。。。用于 u-boot.img 加载的打印命令

可能与 tispl.bin 文件并非无符号数有关

你好、Rachel、

不成问题。我在启动 GP 器件时也看到它。

由于您使用的是定制板、您是否遵循了：定制板启动指南？

此外、运行 bitbake 命令时、您需要构建什么机器？

此致！
Jared

尊敬的 Jared：

在电路板中、我们更改了 UART 端口、我使用了 https://www.ti.com/lit/an/spradg5/spradg5.pdf?UART=1723883607340 ts 指南来进行这些更改。
我可能需要为其添加更多更改、我将对其进行调试。

用于构建的机器是 Ubuntu 22.04。

谢谢！
Rachel

你好、Rachel、

请告诉我您的调试结果。如果 UART 端口有问题、您将不会看到任何引导日志(符合预期)。

此外、当我说机器时、我是指 bitbake 变量。例如、j784s4-EVM

此致！

尊敬的 Jared：

我成功在定制板上加载了 ti-processor-sdk-linux-adas-j784s4-evm-10_00_00_08 SDK 的 tiboot3.bin、tispl.bin_unsigned、u-boot.img_unsigned 文件(在根据 https://www.ti.com/lit/an/spradg5/spradg5.pdf?UART=1723883607340 指南更改了 ts 端口后)。

但我仍然无法成功加载 Yocto 编译的 tispl.bin 文件、它卡在"在 ARM64内核上启动 ATF……"
也许我没有在 OPTEE 中正确更改 UART 端口？
在 SDK 中、我使用了"export CFG_CONSOLE_UART=0x8"命令、但在 Yocto 编译中、我在 core/arch/arm/plat-k3/conf.mk 中更改了
+#CFG_CONSOLE_UART？= 0
+CFG_CONSOLE_UART = 2

可以帮帮我吗？

我使用了 MACHINE=j784s4-EVM。

谢谢！
Rachel

你好、Rachel、

您是否已查看 TDA4：定制电路板启动指南？

包含有关切换 UART 控制台的说明。

尊敬的 Jared：

是的、我在 SDK 中更改了、它对我很有用。

我的问题是如何在 bitbake 命令中进行"CFG_CONSOLE_UART=0x8"更改？

我在"MACHINE=j784s4-evm bitbake -f -c compile trusted-firmware-a" 命令中使用。

谢谢！
Rachel

你好、Rachel、

在 meta-ti 中、它看起来像是由 optee-os-ti-overrides.inc:设置 CFG_CONSOLE_UART

$ grep CFG_CONSOLE_UART -r ./*
./meta-ti/meta-ti-bsp/recipes-security/optee/optee-os-ti-overrides.inc:EXTRA_OEMAKE:append:k3 = "${@ ' CFG_CONSOLE_UART='+ d.getVar('OPTEE_K3_USART') if d.getVar('OPTEE_K3_USART') else ''}"

然后、好像在 j784s4-evm.conf 中设置了 OPTEE_K3_USART：

$ grep OPTEE_K3_USART -r ./*
...
./meta-ti/meta-ti-bsp/conf/machine/j784s4-evm.conf:OPTEE_K3_USART = "0x8"
...
./meta-ti/meta-ti-bsp/recipes-security/optee/optee-os-ti-overrides.inc:EXTRA_OEMAKE:append:k3 = "${@ ' CFG_CONSOLE_UART='+ d.getVar('OPTEE_K3_USART') if d.getVar('OPTEE_K3_USART') else ''}"

您能否尝试在此处设置该值？

此致！
Jared

尊敬的 Jared：

我做了以下更改：

In meta-ti/meta-ti-bsp/conf/machine/j784s4-evm.conf file:

from TFA_K3_USART = "0x8" to TFA_K3_USART = "0x1"
from OPTEE_K3_USART = "0x8 to "OPTEE_K3_USART = "0x2"

In trusted-firmware-a/2.10+git/git/plat/ti/k3/include/platform_def.h file:

-#define K3_USART_BASE                  (0x02800000 + 0x10000 * K3_USART)
+#define K3_USART_BASE                  (0x02820000 + 0x10000 * K3_USART)

它能为我效劳。
