It should work.

1. Why I can&#39;t use redhat 9 for Building nios-linux?

could i upate the gcc for redhat 9?

2. about jffs2 &#39;s problems on uClinux 2.4.22.

We have 2MB SST39LV1601 flash and The flash partition is mounted as a jffs2 partition. When we try to remove and copy some files to and from the filesystem which is mounted as a root filesystem it occasionally gives the following warning:

(1) jffs2_read_inode(): No data nodes found for inode# 181.

then, this filesystem some files can&#39;t be accessed to and giving this warning when booting.

(2) sometimes it gives the following warning :

JFFS2: Erase block at 0x0008b000 is not formatted. It will be erased

.....

Because my application needs sending and receiving data realtime,it run seems normal,but it happens some delay and crash sometimes.

What are possible causes of that gives this warning?

ONE question for a thread, please.

Your question should be on the topic.

Just "Beginner for Nios2" is not a good title.

1. Don&#39;t mix up Nios and Nios II.

They are almost totally different.

You should not work on Nios, unless you are maintaining an old product.

Yes, you can install the Nios2 binary toolchain from the wiki and develpe nios2 uclinux on Redhat 9.

But Redhat 9 is OBSOLETE. It is not maintained.

The some tools on Redhat 9 are old, and can not run buildroot.

2. jffs2 on kernel 2.4.22,

NO comment.

Nios2 uclinux use kernel 2.6 .
