如何在荔枝派 zero 的SDC1上使用RTL8723BS WIFI模块
1. dts如何修改
2. 为什么驱动只能选择（M）不能（*）
能不能分享一下，怎样使能，并成功使用8723bs的
简单，好用。
这个改完以后，为什么开机后，直接进去的目录就变了呢
zImage是自解压缩的镜像，可以随意放到内存的任意位置
Image属于未加压镜像需要放到指定内存位置，如0x40008000(arm32)，参考内核内存映射模型
具体代码参照lds链接脚本，和stext的代码
还是有点不太懂，官网上的spiflash启动，uboot需要这样改动。烧写到flash0x110000 的是内核zImage，为啥要加载到0x41000000 ，有没有具体点的信息和设置说明，能详细讲解一下嘛？
#define CONFIG_BOOTCOMMAND "sf probe 0; " \
"sf read 0x41800000 0x100000 0x10000; " \
"sf read 0x41000000 0x110000 0x400000; " \
"bootz 0x41000000 - 0x41800000"
#define CONFIG_BOOTARGS "console=ttyS0,115200 earlyprintk panic=5 rootwait " \
"mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2"
为啥要将内核的内容读到内存的0x41000000，有没有具体的说明和计算，文档啥的学习一下，是在哪个地方指定的？
重新用 mkfs.jffs2 制作jffs2镜像文件，
烧录到 flash指定地方(地址由你的flash分区确定)
如果烧录软件没有校验功能，最好烧录完能读回来手动比较。
我已经制作很多次了呢，老板，32m的flash，是因为哪些不匹配才会有这些oops嘛？
咦，昨天回复你了啊，可能是jffs2文件系统问题
木有解决啊，需要我换个系统嘛？

how to send you ?
please email me
hello? ni zi liao fa lun tan hao ma ?
找到问题了，因为spiflash 4k擦除问题。
为啥会有这个问题？
你问的应该是dvp，这个是支持的
dvp？怎么配置，有没有文档啥的
有没有具体的教程啥的，需要学习一些，谢谢。@晕哥
直接修改Linux源码目录下面的.config文件即可。
你是软件命令reboot? 主动热重启可以改下代码: https://whycan.cn/t_534.html#p1447
热重启还好可以按照上面的处理，
如果是死机就有有点麻烦，
即使有外部看门狗(如max811)拉低 V3s 8PIN的也不能重启成功，除非flash电源脚也可以用看门狗控制。
所以我现在用16PIN 的 W25Q256, 这样每次都能可靠复位了,
把FLASH的 RESET# 引脚和 V3s的 RESET# 引脚短路到外部看门狗。
我说的应该是软件命令reboot，但是后面你说的那个应该后面也会遇到，你说的flash和v3s的reset引脚短路到外部看门狗是什么意思，有点不太了解
如题，有没有具体的解决方法
是使用了32M flash，在重启的时候，没有退出4-byte地址模式导致。（因为板子上没有PMU，没有对flash进行复位）？应该怎么操作？
如题，有没有具体的解决方法
@njitnjit bootargs 中间少了一个逗号。
正确的应该是啥样的？，能不能贴出来我对比一下
dd if=rootfs.squashfs of=flashimg.bin bs=1K seek=5184 conv=notrunc
启动系统后，挂在剩余的分区jffs2到workdir目录，这里的/workdir，请在制作squashfs文件系统之前mkdir，不然启动后squashfs为只读的，就不能新建文件夹了，这样workdir目录就变成可读写的了
mount -n -t jffs2 /dev/mtdblock4 /workdir
如果想使用overlayfs，请在制作squashfs文件系统之前新建merged 和 overlay
启动系统后
mount -n -t jffs2 /dev/mtdblock4 /overlay
mkdir /overlay/upperdir /overlay/workdir
mount -n -t overlay overlayfs:/overlay -o lowerdir=/,upperdir=/overlay/upperdir,workdir=/overlay/workdir /merged/
这样upperdir的目录就是/overlay/upperdir，lowerdir就是根目录
在你未做修改之前 可以ls查看一下，ls /merged和ls /目录是一样的内容，
这样就可以在/merged添加修改你的东西了
后面我的觉麻烦，而且研究的不透彻就没有使用overlay了
问一下，这里说的启动系统是板子上电是吧，还有这些这些命令，是在板子上进行操作嘛？
参考晕哥这个帖子: https://whycan.cn/t_444.html
应该是解决了，是添加，我直接覆盖原来的了
官网上是这样的
sunxi-fel增加对16M以上Flash的支持
由于SPI flash 的地址是24bit，也就是最大16M 地址空间，所以对于32M flash，需要增加bank切换支持。
uboot中有 CONFIG_SPI_FLASH_BAR 选项可以使能bank切换。
但是sunxi-fel中尚未支持，所以下载的时候超出16M会循环覆盖掉。
这里介绍对sunxi-fel增加16M以上flash支持的方法。
u-boot的支持
drivers/mtd/spi/spi_flash.c
static int write_bar(struct spi_flash *flash, u32 offset)
{
u8 cmd, bank_sel;
int ret;
bank_sel = offset / (SPI_FLASH_16MB_BOUN << flash->shift);
if (bank_sel == flash->bank_curr)
goto bar_end;
cmd = flash->bank_write_cmd;
ret = spi_flash_write_common(flash, &cmd, 1, &bank_sel, 1);
if (ret < 0) {
debug("SF: fail to write bank register\n");
return ret;
}
bar_end:
flash->bank_curr = bank_sel;
return flash->bank_curr;
}
sunxi-fel的支持
fel-spiflash.c
#define CMD_WRITE_ENABLE 0x06
#define SPI_FLASH_16MB_BOUN 0x1000000

size_t bank_curr = 0;
void aw_fel_spiflash_write_helper(feldev_handle *dev,

size_t erase_size, uint8_t erase_cmd,
size_t program_size, uint8_t program_cmd)
{
uint8_t *buf8 = (uint8_t *)buf;
size_t max_chunk_size = dev->soc_info->scratch_addr - dev->soc_info->spl_addr;
size_t cmd_idx, bank_sel;
if (max_chunk_size > 0x1000)
max_chunk_size = 0x1000;
uint8_t *cmdbuf = malloc(max_chunk_size);
cmd_idx = 0;

//add bank support
{
cmd_idx = 0;
bank_sel = offset /SPI_FLASH_16MB_BOUN;
if (bank_sel == bank_curr)
goto bar_end;

cmdbuf[cmd_idx++] = 2;
cmdbuf[cmd_idx++] = CMD_EXTNADDR_WREAR;
cmdbuf[cmd_idx++] = offset >> 24;
/* Emit wait for completion */
cmdbuf[cmd_idx++] = 0xFF;
cmdbuf[cmd_idx++] = 0xFF;
/* Emit the end marker */
cmdbuf[cmd_idx++] = 0;
cmdbuf[cmd_idx++] = 0;
aw_fel_write(dev, cmdbuf, dev->soc_info->spl_addr, cmd_idx);
aw_fel_remotefunc_execute(dev, NULL);
bar_end:
bank_curr = bank_sel;
}
cmd_idx = 0;
重新编译sunxi-fel后就可以烧录32M flash了~
有没有大师，帮忙看一下哇
进入后查看，好像是根文件系统没有挂载起来？
还有这个问题，我用其他电脑烧录进去后，输入不了U-Boot SPL 2017.01-rc2 (May 21 2020 - 07:47:08)

有个疑问，网上的根文件系统，有区分flash的大小嘛？应该都可以把？因为在配置buildroot的时候，没有选择flash的大小，就是我是32m的flash，下载打包好的个根文件系统，也只是在打包的时候有区分是吧
还有个疑问，网上的镜像，有区分flash的大小嘛？应该都可以把？因为在配置buildroot的时候，没有选择flash的大小啊？
选了
你buildroot选择的不是EXT4吧
在哪里选择，在哪里看？
我的也是编译不成功，正在查找原因。
晕哥帮忙看看哇？

希望能够追随晕哥，早日像晕哥一样住上大别墅！
请问楼主按最后这样解决问题了嘛， 可以启动了吗？还是要再修改什么？
所以这个最后怎么样了啊，可以用了嘛？
确实无私，向晕哥学习，我还是小白，努力学习中
请问楼主，设备树中需要修改什么吗？我的电脑端一直没有出现新设备
