FlashROM读SPI Flash出现问题

Default
#1

如题，Flash是Winbond W25Q128，flashrom识别成功但读写操作时提示"ioctl: Message too long" 。
接线方法是按照树莓派的接法，CS接到了CS1上面，试过修改dts文件把：

spi-max-frequency = <40000000>;

改成

spi-max-frequency = <20000000>;

依然报错。

同时也尝试过在文件底下加上一个软SPI（spi-gpio）但flashrom直接无法识别了，可能是我写的不对：

	spi {
		compatible = "spi-gpio";
        	#address-cells = <0x1>;
        	ranges;

		gpio-sck = <&gpio0 15 0>;
		gpio-miso = <&gpio0 16 0>;
		gpio-mosi = <&gpio0 17 0>;
		cs-gpios = <&gpio0 14 0>;
		num-chipselects = <1>;
		status = "ok";
      
          spidev@2{
                         compatible = "spidev";
                         reg = <0>;
                         #address-cells = <1>;
                         #size-cells = <0>;
                         spi-max-frequency = <2000000>;
               };
	};

详细flashrom信息如下：

@mango 哈哈还不算肉身翻墙，只是上个学

#3

@huming2207 肉身在墙外着实令人羡慕！
软件多找lintel，硬件我来，哈哈

#4

@mango 我平时不在国内，打板子不太方便（而且画板子画的一般吧，之前玩脱了两次浪费几十块钱），你们如果能做是最好的哈哈哈

我过后试试把FlashROM的所有stdout输出信息魔改一下搞成带JSON格式的，然后GUI用WPF或者Electron做个跨平台的app，难度应该不大。

#5

@huming2207 赶快把这个工程师神器搞出来

#6

@mango 我倒是奇怪为毛淘宝上一堆用stm32做烧录器，然后代码写得跟我一样屎😂，客服态度非常差，驱动还不签名，英文版Win10用他们的上位机app一堆bug，读写大文件似乎还放到UI线程做，然后UI卡死。而且关键是很多做这个开发的人都是在Linux环境下干活儿，他们也不写个Linux的上位机app。

而且好像淘宝上搞FT232/2232/4232的都是用来做JTAG debugger，没有像那些烧录器一样带个芯片座子……如果有谁做个烧录器外形的FT232板子，顺便再引出JTAG的那种标准接口，魔改一个FlashROM，用Electron或者Qt或者GTK什么的做个好看好用点的GUI，80块以内价格，我会买。

@mango 大佬如果感兴趣的话做一个？:joy:

#7

好的flashrom的feed来了，在源码根目录的feeds.conf.default最后一行加上：

src-git flashrom https://github.com/huming2207/openwrt-flashrom-chromium.git

即可

#8

@huming2207 我用ch341烧整个大固件，记得至少10分钟，看那进度条我都以为死机了。。。。。。。

#9

实际多次写入不同的、带OpenWrt的镜像大概两分多钟，还算理想。
还有如果配合ft232系列，有空重新折腾一下flashrom那个ft232适配代码应该速度会更快。

#10

@mango 是的

谷歌ChromiumOS fork版的FlashROM效果会更好，因为他能对比镜像和flash里面的内容，然后自动跳过一些不需要写入的block。

我略改了下那个谷歌版FlashROM，加了一两个原版FlashROM的linux_spi
buffer相关的patch，写入16MB最差情况5分1秒，最好情况1分半。

等会儿我忙完了就做个openwrt feed贴上来

#11

@huming2207 听说模拟的SPI比ch341那种烧写器都快？:sweat_smile:

#12

……打错几个字修改了一下，再补充一点，可能需要修改spidev的buffer size，否则flashrom可能认得出flash芯片，但无法进行读写操作。我设置到最大值65535 bytes，测了几十回没问题。

#13

@mango 不好意思前几天不在深圳没看到您的跟帖

情况是这样的，如果是mainline的openwrt，直接改dts的：

		gpio-sck = <&gpio0 15 0>;
		gpio-miso = <&gpio0 16 0>;
		gpio-mosi = <&gpio0 17 0>;
		cs-gpios = <&gpio0 14 0>;

里面最后一位的0写错了，改成1即可，即<&gpio0 xx 0>改成<&gpio0 xx 1>

如果是MTK的OpenWrt，比如@mango 他们给的那个openwrt，则可能需要手动用reg工具改一下寄存器。
具体说明教程参见此帖：https://community.onion.io/topic/1266/how-to-switch-agpio-gpio-18-19-omega2-fw-vs-lede-build，
没记错的话命令应该是reg w 0x1000003C 0xFE01FF。

此外还需要注意：

  1. spi-max-frequency建议改大一点，如果只是用flashrom的话可以直接设置成20000000（加个0，翻10倍）速度快很多
  2. 建议使用谷歌ChromiumOS的flashrom，不然写入/擦写速度很慢。稍后我会做一个openwrt feed，到时候贴上来。

同时感谢@mango 大佬以及某些不方便透露姓名的大佬们的帮助！以前大一大二瞎折腾C# Java啥的没怎么折腾嵌入式，所以不够熟练……:joy:
