芯片：W25N01GVZEIG
一、硬件介紹
datasheet上的描述：
- SLC工藝
- 2KB*65536頁
- 10萬次擦寫次數(shù)
焊好以后用CH341A讀了一下
V3s的啟動(dòng)順序
上面這張圖描述了soc啟動(dòng)的四個(gè)順序，分別是usb啟動(dòng)、sd卡啟動(dòng)、spi norflash啟動(dòng)、spi nandflash啟動(dòng)四種方式。前面的測試中一直走的是sd卡啟動(dòng)，但是從成本和穩(wěn)定性上說，spi nandflash其實(shí)是最合適的。
sd 卡需要卡座拔插，在震動(dòng)環(huán)境下不穩(wěn)定，容易接觸不良，容量大，其實(shí)也貴，相當(dāng)于EMMC。
spi nor flash容量一般在16MB左右，也有32MB和64MB的，但是價(jià)格較貴。
2023年9月16日15:36:26，在某寶上數(shù)據(jù)對(duì)比一下
| 容量 | 接口 | 型號(hào) | 價(jià)格 |
|---|---|---|---|
| 16MB | spi nor flash | W25Q128JVSIM | 3.8￥ |
| 32MB | spi nor flash | W25Q256JVEIQ | 7.1￥ |
| 128MB | spi nand flash | W25N01GVZEIG | 4.0￥ |
| 256MB | spi nand flash | W25N02KVZEIR | 5.9￥ |
所以，16M/32M 的spi nor flash 真的沒有什么優(yōu)勢。做非常簡單的應(yīng)用還可以，其他就算了吧。故以后自己玩也要玩nand flash吧，nor flash沒有什么應(yīng)用場景。
有興趣可以看看，我之前的記錄：
全志V3s學(xué)習(xí)記錄：Nor Flash使用（一）
全志V3s學(xué)習(xí)記錄：Nor Flash使用（二）
二、驅(qū)動(dòng)支持
U-Boot驅(qū)動(dòng)
使用：http://sources.buildroot.net/uboot/u-boot-2022.04.tar.bz2
主線 Linux 驅(qū)動(dòng)已經(jīng)支持
4.19 及其以后的版本支持 spi nand
https://github.com/torvalds/linux/blob/v4.19/drivers/mtd/nand/spi/winbond.c
目前主線Linux已經(jīng)支持winbond:W25N01GVZEIG，如下：
在線Linux Kernel代碼：https://elixir.bootlin.com/linux/v5.2.20/source/drivers/mtd/nand/spi/winbond.c
static const struct spinand_info winbond_spinand_table[] = {
SPINAND_INFO("W25M02GV", 0xAB,
NAND_MEMORG(1, 2048, 64, 64, 1024, 20, 1, 1, 2),
NAND_ECCREQ(1, 512),
SPINAND_INFO_OP_VARIANTS(&read_cache_variants,
&write_cache_variants,
&update_cache_variants),
0,
SPINAND_ECCINFO(&w25m02gv_ooblayout, NULL),
SPINAND_SELECT_TARGET(w25m02gv_select_target)),
SPINAND_INFO("W25N01GV", 0xAA,
NAND_MEMORG(1, 2048, 64, 64, 1024, 20, 1, 1, 1),
NAND_ECCREQ(1, 512),
SPINAND_INFO_OP_VARIANTS(&read_cache_variants,
&write_cache_variants,
&update_cache_variants),
0,
SPINAND_ECCINFO(&w25m02gv_ooblayout, NULL)),
};
三、燒錄工具 xfel
之前燒錄spi nor flash的時(shí)候，使用的是sunxi-fel工具，如果需要燒錄spi nand flash image，就需要xfel
https://github.com/xboot/xfel
或者 git https://github.com/xboot/xfel.git
下載直接選main，解壓、直接make就可以了。
- 解壓
makesudo make install

這就是ubuntu識(shí)別出來進(jìn)入U(xiǎn)SB升級(jí)模式的V3s了。
簡單使用一下：
liefyuan@ubuntu:~$ xfel spinand

四、構(gòu)建U-Boot（官方的Uboot）
地址：http://sources.buildroot.net/uboot/u-boot-2022.04.tar.bz2
驅(qū)動(dòng)是支持的：
liefyuan@ubuntu:~/V3s/u-boot-2022.04$ find ./ -name "winbond.c"
./drivers/mtd/nand/spi/winbond.c
先編譯一下
先編譯一下看看有沒有什么問題
make ARCH=arm LicheePi_Zero_defconfig
make ARCH=arm menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
最后一步報(bào)錯(cuò)了，交叉編譯器版本太老了。
*** Your GCC is older than 6.0 and is not supported
arch/arm/config.mk:74: recipe for target 'checkgcc6' failed
make: *** [checkgcc6] Error 1
換個(gè)高版本的交叉編譯器！
再裝個(gè)軟件：sudo apt install swig
初步編譯成功了！
開始spi nand flash 代碼層面的適配
拷貝spl_spinand_sunxi.c到arch/arm/mach-sunxi目錄下，文件地址：
https://github.com/bamkrs/openwrt/blob/dolphinpi-spinand/package/boot/uboot-sunxi/src/arch/arm/mach-sunxi/spl_spinand_sunxi.c
spl_spinand_sunxi.c需要做一些修改：
- 添加頭文件
- 添加函數(shù)調(diào)用參數(shù)
// add by liefyuan
#include <image.h>
#include <linux/delay.h>
ret = spl_parse_image_header(spl_image, bootdev, header); // modified by liefyuan
然后在，arch/arm/mach-sunxi/Kconfig 文件中添加內(nèi)容：
config SPL_SPINAND_SUNXI
bool "Support for SPI Nand Flash on Allwinner SoCs in SPL"
depends on MACH_SUN8I_V3S
help
Enable support for SPI Nand Flash. This option allows SPL to read from
sunxi SPI Nand Flash. It uses the same method as the boot ROM, so does
not need any extra configuration.
1043gg 處添加吧
然后在 arch/arm/mach-sunxi/Makefile添加 spl_spinand_sunxi.c的編譯選項(xiàng)
ifdef CONFIG_SPL_BUILD
obj-$(CONFIG_MACH_SUNIV) += dram_suniv.o
obj-$(CONFIG_DRAM_SUN4I) += dram_sun4i.o
obj-$(CONFIG_DRAM_SUN6I) += dram_sun6i.o
obj-$(CONFIG_DRAM_SUN8I_A23) += dram_sun8i_a23.o
obj-$(CONFIG_DRAM_SUN8I_A33) += dram_sun8i_a33.o
obj-$(CONFIG_DRAM_SUN8I_A83T) += dram_sun8i_a83t.o
obj-$(CONFIG_DRAM_SUN9I) += dram_sun9i.o
obj-$(CONFIG_SPL_SPI_SUNXI) += spl_spi_sunxi.o
obj-$(CONFIG_SUNXI_DRAM_DW) += dram_sunxi_dw.o
obj-$(CONFIG_SUNXI_DRAM_DW) += dram_timings/
obj-$(CONFIG_DRAM_SUN50I_H6) += dram_sun50i_h6.o
obj-$(CONFIG_DRAM_SUN50I_H6) += dram_timings/
obj-$(CONFIG_DRAM_SUN50I_H616) += dram_sun50i_h616.o
obj-$(CONFIG_DRAM_SUN50I_H616) += dram_timings/
obj-$(CONFIG_SPL_SPINAND_SUNXI) += spl_spinand_sunxi.o
endif
繼續(xù)，在 arch/arm/dts/sun8i-v3s-licheepi-zero.dts文件中添加spi0的內(nèi)容：
&spi0 {
pinctrl-0 = <&spi0_pins>;
pinctrl-names = "default";
status = "okay";
flash@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "spi-nand";
reg = <0>;
spi-max-frequency = <50000000>;
};
};
最后，在 include/configs/sun8i.h添加內(nèi)容，要在#include <configs/sunxi-common.h>之前添加。
#ifdef CONFIG_BOOTCOMMAND
#undef CONFIG_BOOTCOMMAND
#endif
#ifdef COFNIG_BOOTARGS
#undef CONFIG_BOOTARGS
#endif
#define CONFIG_BOOTCOMMAND "mtd read spi-nand0 0x41800000 0x100000 0x20000; " \
"mtd read spi-nand0 0x41000000 0x120000 0x500000; " \
"bootz 0x41000000 - 0x41800000"
#define CONFIG_BOOTARGS "console=ttyS0,115200 earlyprintk panic=5 rootwait " \
"mtdparts=spi0.0:1M(uboot)ro,128k(dtb)ro,5M(kernel)ro,-(rootfs) ubi.mtd=3 root=ubi0:rootfs rw rootfstype=ubifs"
修改menuconfig配置
命令：make ARCH=arm menuconfig
ARM architecture配置Support for SPI Nand Flash on Allwinner SoCs in SPL
Boot options 取消 Enable boot arguments
打開Device Drivers下面的SPI Support
在Device Drivers下面 MTD Support 中勾選 Enable MTD layer Driver Model for MTD driver
在Command line interface的Device access commands勾選 mtd，這樣后續(xù)生成的uboot中才會(huì)有MTD相關(guān)的命令，類似于SPI NOR Flash添加的sf命令
Environment 取消勾選 Environment is in SPI flash，這個(gè)選項(xiàng)是在打開SPI Support之后才會(huì)被看到
OK，更改完畢。
再次編譯一下就OK了。
make ARCH=arm LicheePi_Zero_defconfig
make ARCH=arm menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
修改uboot輸出文件使其可以在spinandflash上運(yùn)行
此時(shí)，u-boot-sunxi-with-spl.bin還不能被直接下載到nand flash。因?yàn)閂3s默認(rèn)從spi nand flash加載page內(nèi)容，是1個(gè)page加載1KB。我使用的是winbond的W25N01GVZEIG，它的page是2KB。
腳本地址：https://github.com/bamkrs/openwrt/blob/dolphinpi-spinand/target/linux/sunxi/image/gen_sunxi_spinand_onlyboot_img.sh
運(yùn)行命令：
./gen_sunxi_spinand_onlyboot_img.sh split.bin u-boot-sunxi-with-spl.bin 2048 128
其中split.bin代表生成的目標(biāo)文件，u-boot-sunxi-with-spl.bin表示剛剛編譯好的uboot文件，2048代表page大小，單位是byte，而128則代表block大小，單位是k byte。
下載修改后的uboot文件到spinandflash文件
liefyuan@ubuntu:~/V3s/u-boot-3s-spi-experimental$ sudo xfel spinand erase 0x0 0x100000

五、構(gòu)建Linux Kernel
源碼：https://github.com/Lichee-Pi/linux/tree/zero-5.2.y
修改設(shè)備樹
修改 chosen
chosen {
bootargs = "console=ttyS0,115200 earlyprintk panic=5 rootwait mtdparts=spi0.0:1M(uboot)ro,128k(dtb)ro,5M(kernel)ro,-(rootfs) ubi.mtd=3 root=ubi0:rootfs rw rootfstype=ubifs";
};
增加SPI0節(jié)點(diǎn)

&spi0 {

menuconfig里面配置增加驅(qū)動(dòng)支持

六、構(gòu)建文件系統(tǒng)
現(xiàn)成的文件系統(tǒng)：
鏈接：https://pan.baidu.com/s/1-HMjT5BCYq0aImIJcQyJlw
提取碼：lief
–來自百度網(wǎng)盤超級(jí)會(huì)員V5的分享
系統(tǒng)名是：root
無密碼
spi nand flash 一般使用的文件系統(tǒng)是ubifs文件系統(tǒng)。涉及到兩個(gè)工具
第一步：先用mkfs.ubifs生成rootfs_ubifs.img文件，其中-d target就是根文件目錄的位置：
sudo mkfs.ubifs -x lzo -F -m 2048 -e 126976 -c 732 -o rootfs_ubifs.img -d target
第二步：用ubinize生成最終的ubi.img
sudo ubinize -o ubi.img -m 2048 -p 131072 -O 2048 -s 2048 ./ubinize.cfg -v
ubinize.cfg文件
[rootfs-volume]
mode=ubi
image=rootfs_ubifs.img
vol_id=0
vol_size=92946432
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize
vol_alignment=1
有了ubi.img之后，就可以使用xfel工具燒錄了。
sudo xfel spinand erase 0x620000 0x79DFFFF
sudo xfel spinand write 0x620000 ubi.img
燒錄成功后，上電信息：
