[U-Boot] Problem with mounting a jffs2 partition on flash.

Hi Wolfgang,

Thank you for your quick reply.

Yes, I'm aware that jffs2 is quite old and ubifs is a successor of jffs2, but the reason is that current Linux Kernel has no support for UBI.
It means that if will use UBI in U-boot we can't see the contents in Lunix env after it starts.
I understand that it should have solution, but it requires recompiling Linux kernel which is also time consuming.

So, for a proof of concept I decided to make it work with jffs2.

Yes, current logs are from OLD U-boot version.

U-Boot launches, but after that it is hanging.
U-Boot 2016.01 (Feb 05 2016 - 14:15:47 +0100)

CPU:   Altera SoCFPGA Platform
FPGA:  Altera Arria V, D5, version 0x0
BOOT:  QSPI Flash (3.0V)
       Watchdog enabled
I2C:   ready
DRAM:

I will try to tackle this problem also.
However, I must say that I don't have much experience with U-Boot, so maybe I'm missing something obvious?

Can you please share some examples of correct configuration for such use case (jffs2 partition on NOR flash with SPI)?
I spent some time digging into the code, enabling different defines, so now it is complete mess in my sources.
