The published RNDIS * spec is ambiguous, incomplete, and needlessly complex. Variants such as * ActiveSync have even worse status in terms of specification. * * In short: it's a protocol controlled by (and for) Microsoft, not for an * Open ecosystem or markets. Linux supports it *only* because Microsoft * doesn't support the CDC Ethernet standard. * * The RNDIS data transfer model is complex, with multiple Ethernet packets * per USB message, and out of band data. The control model is built around * what's essentially an "RNDIS RPC" protocol. It's all wrapped in a CDC ACM * (modem, not Ethernet) veneer, with those ACM descriptors being entirely * useless (they're ignored). RNDIS expects to be the only function in its * configuration, so it's no real help if you need composite devices; and * it expects to be the first configuration too. * * There is a single technical advantage of RNDIS over CDC Ethernet, if you * discount the fluff that its RPC can be made to deliver: it doesn't need * a NOP altsetting for the data interface. That lets it work on some of the * "so smart it's stupid" hardware which takes over configuration changes * from the software, and adds restrictions like "no altsettings". * * Unfortunately MSFT's RNDIS drivers are buggy. They hang or oops, and * have all sorts of contrary-to-specification oddities that can prevent * them from working sanely. Since bugfixes (or accurate specs, letting * Linux work around those bugs) are unlikely to ever come from MSFT, you * may want to avoid using RNDIS on purely operational grounds. * * Omissions from the RNDIS 1.0 specification include: * * - Power management ... references data that's scattered around lots * of other documentation, which is incorrect/incomplete there too. * * - There are various undocumented protocol requirements, like the need * to send garbage in some control-OUT messages. * * - MS-Windows drivers sometimes emit undocumented requests. */ struct f_rndis { struct gether port;

大佬，你是将下面这部分的定义和有关rndis_dl_max_pkt_per_xfer 这个变量的部分去掉了吧，这样做的话有什么影响吗

请问是如何修改的?
我修改了两个地方，一个是设备树文件sun3iw1p1-c200s-F1C200s.dts文件
nor_flash@0 {
#address-cells = <1>;
#size-cells = <1>;
将compatible = "st,m25p64";
改为compatible = "macronix,mx25l12805d","jedec,spi-nor";
spi-max-frequency = <50000000>;
reg = <0>; /* Chip select 0 */
};一个是m25p80.c文件
{ "mx25l12805d", INFO(0xc22018, 0, 64 * 1024, 256, 0) },
改为
{ "mx25l12805d", INFO(0x0b4018, 0, 64 * 1024, 256, 0) },启动日志

MagicKind，麻烦重新开帖，把你的日志和.config配置都贴上，否则谁能猜中?
好的，麻烦大佬帮忙看一下了
求助F1C200S启动时，无法挂在根文件

MagicKind 说：飞翔工控 说：https://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html
#define ENXIO 6 /* No such device or address */
/dev/mtdblock4 设备不存在
这个不是系统会自己创建的吗
要追溯起来，可复杂了。
要提供dtb/bootargs mtdparts传入分区参数，要勾选mtd和mtdblock驱动
这个都勾上了的
MagicKind 说：大佬，请问下，你知道VFS: Cannot open root device "mtdblock4" or unknown-block(0,0): error -6的问题是什么吗
