BPI-R4 BSP与U-Boot使用求助

Banana Pi Router design BPI-R4(MT7988)

我使用这里的代码编译U-Boot成功，但是编译Kernel失败了(wifi-mt7996e驱动)。错误如下：

Build failed!

U-Boot编译成功后会产生u-boot-mt/build_emmc/u-boot.bin，u-boot-mt/build_sdmmc/u-boot.bin两个uboot镜像，我怎么把u-boot.bin刷到nand flash中，另外bsp 6.1中的u-boot和bsp 5.4中的kernel如何才能编译成功。

这个6.1的bsp似乎没有wifi的驱动支持？

还有nand flash中的u-boot损坏是否会影响sd卡启动功能？

I used the code here to compile U-Boot successfully, but failed to compile the kernel (wifi-mt7996e driver).The error is as follows:

 Build failed!

After U-Boot is successfully compiled, two uboot images will be generated: u-boot-mt/build_emmc/u-boot.bin and u-boot-mt/build_sdmmc/u-boot.bin. How can I flash u-boot.bin to nand flash? In addition, how can the u-boot in bsp 6.1 and the kernel in bsp 5.4 be compiled successfully?

This 6.1 bsp does not seem to have wifi driver support?

Also, will the damage of u-boot in nand flash affect the sd card boot function?

It is stated in the BPI document that there is no MT76 wifi driver in the 6.1 kernel

4

please use the build.sh script to compile all images.

I always use build.sh.

fatal error: stdarg.h: No such file or directory

I solved this problem by create stdarg.h in wifi-mt7996e/backports-6.5/include,the stdarg.h file contents is:

// SPDX-License-Identifier: GPL-2.0-or-later
#ifndef _LINUX_STDARG_H
#define _LINUX_STDARG_H

typedef __builtin_va_list va_list;
#define va_start(v, l)	__builtin_va_start(v, l)
#define va_end(v)	__builtin_va_end(v)
#define va_arg(v, T)	__builtin_va_arg(v, T)
#define va_copy(d, s)	__builtin_va_copy(d, s)

#endif

is not clean, please run 'make mrproper'

There is no solution to this problem
