Sam9x35 VFS error -19 with JFFS2 RFS compiled with Bulidroot

Hello:
I'm new at embedded linux so i hope be clear enough.

I'm trying to mount LinuxEmbedded software in at91sam9x35ek. I have downloaded Buildroot 2017.08, and then used "menuconfig at91sam9x5ek_dev_defconfig" This configuration sets for NandFlash Use.
After this I only added in Builroot menuconfig the file system option for JFFS2 with these options:

• jffs2 root filesystem
• Flash Type (Parallel flash with 128 kB erase size)
• Do not use Cleanmarker

All other options default. Also got ubifs output compiled because the default config selected it.

With the default U-boot envioronment and some changes to bootcmd i was able to login into buildroot's default rootfs.ubi. But when i changed for using rootfs.jffs2 go errors. Paste Log below:

Some more data:
1- all is flashed with SAM-BA 2.12
2- Option trimffs is not activated for JFFS2 (contrary to UBIFS)
3- No configurations were made to Linux kconfig from Buildroot's config file.(default)
4- To clarify I need JFFS2 because i have an old tool with custom user libraries that only generates JFFS2 rootfilesystems

Questions:

1. What did I do wrong with bootargs environment variable?
2. how do I enter linux if i can't mount the RFS?If possible
3. is there another way of doing this?Mounting jffs2 RFS?
4. Is the flashtype selected for JFFS2 correct?
5. Please add any comment you seem fit

Thanks and Best Regards.-

PD: I did read the "Post Smart" and used Search before posting there was over 450 posts with JFFS2 in the search but I did not found response, only 3 results with VFS error.
