Hello all
I'm trying to add jffs2 support to a kernel (3c120 dev board) and I'm facing an strange problem. If I checked in jffs2 support in menuconfig, _after_ compiling the kernel core and _while compiling_ the apps , the compile process barfs
|| ( touch mtd-utils/.sgbuilt_user && make -C mtd-utils ) || exit $?
make: se ingresa al directorio `/home/eugenio/uCLinux-MMU/nios2-linux/uClinux-dist/user/mtd-utils'

The strange thing is that it tries to compile mkfs.jffs2 using my x86 gcc compiler :confused: If I try to disable mtd-utils, it doesn't mind; same error while compiling mkfs.jffs2 in mtd-utils which I have previously disabled.... Adding kernel support for MTD and user apps. support for mtd-utils works fine. No errors. It only happens when adding jffs2 kernel support and while compiling mkfs.jffs2 (mtd-utils enabled or not) Any hints? TIA

The solution is here:

Thanks very much Urmel !!!!!!! \o/
i have success compiling the kernel .......... i add this file system in config.c => mtd_partition nios2_partitions[] { .name = "fpga", .size = 0x0200000, .offset = 0x0, }, { .name = "nios_baremetal", .size = 0x0200000, .offset = 0x01C00000, }, { .name = "uImage1", .size = 0x00400000, .offset = 0x02000000, }, { .name = "romfs", .size = 0x01400000, .offset = 0x04400000, } but in uClinux booting i have this problem physmap platform flash device: 04000000 at 0c000000 physmap-flash physmap-flash.0: map_probe failed do you have any ideia ???????? thank you so much !!!!!- Mark as New

Hi Franz,
you are welcome. Can you also post the complete boot message concerning the implementation of the jffs2? For example the block size (16 or 8 bit) could be a reason. But for simplicity I would just add only one or two partitions so it is easier to look for a possible error in flash size and offset. Urmel- Mark as New

Hello all !!!! good news!!!!!!!!
now i have success booting from the flash ....!!!! \o/ i use this commands elf2flash --base=0x0c000000 --end=0x10000000 --reset=0xe000000 --boot=~/altera/10.1/nios2eds/components/altera_nios2/boot_loader_cfi.srec --input=zImage --output=zImage.flash --verbose and nios2-flash-programmer --base=0xc000000 zImage.flash --instance=0 -g and it works !!!!! and now another problem....... my system is a multicore system ........ i have 2 cpus in my project i one cpu i running the uClinux... and another cpu i running nios2 with the an374 from altera...... its everything works fine ..... but now i have to writing in flash the nios2 software........... another cpu have a reset vector with offset 0x1c00000 how can i write the software without loose linux software...????? thank you very much ....

Are you suggesting that the other CPU does not use an OS at all ?
If the CPUs don't share any resources this should work. Of course here the second CPU needs its own dedicated address spaces on the Avalon bus and accordingly a different reset vector. If the CPUs are supposed to share any addresses (and thus be able to communicate), things will get more complicated and you should start a new forum thread on this. -Michael- Mark as New

Hi Michael !!!! thanks for reply....!!!
well the 2 cpus share many things but this is work fine !!!! i have success doing the uclinux boot from the flash but now i tying to download to flash a software of another cpu where run the an374.... i do that but now the uclinux cant start......... the an374 starts but another cpu show this...Uncompressing Linux....
ERROR

I think it might be the mapping memory in config.c...... what do you think??? i use the default parameters.... {

.offset = 0x00000000,

If both CPUs try to start Linux, things are going very wrong. This can't work as the NIOS Linux is not SMP enabled and will not be in forseeable future, as the NIOS CPU lacks many features necessary for SMP support.
There might be some threads on multiple CPUs here, you might want to read them. And for questions you should start a thread with an appropriate subject line. -Michael- Mark as New

I do have a NEEK, but I am not actively using it right now, as our interests have moved to different targets. So I can only help with some knowledge I collected when I was investigating NIOS and I am still lurking here - just in case. But I can't do any practical tests.

Hi all!!!!!!
good news!!!!!! \o/ i have successfully booting 2 cpus !!! the problem was both starting at the same time!!!! i add a cpu_resetrequest on my linux_cpu and a pio in another cpu..... the linux cpu starts at reset and an374 starts normally after an374 starts i set on nios a pio to starts uclinux cpu.....and voila!!!! now i have the an374 with web browser management......with eth grafics!!! booting from a flash and using only one ethernet port :) now i want to put a snmp agent on it thanks very much all!!!!!

Hi michael .......
was very funny and little hardo to do that....... the linux cpu manage the phy chip ... mdc and mdio....... an374 wait linux configure a phy....... in eth rx i do a verilog block that does a filtering of packets ..by mac (linux mac and an374 mac) in eth tx i do a verilog block that always send a an374 udp flow , if the linux cpu want to send a packet the block wait a interpacket gap send the packet and back send an374 flow .......... i do that usin two dualport ram.....and a monostable.......... i did tests and had very good results..... doesnt lose packets............:) regards Franz wagner- Mark as New

So when sending, you did a hardware block without the Linux driver even knowing about this. Nice !
Does the an374 unit not receive any Ethernet blocks ? -Michael- Mark as New

hi Michael !!
yes... i cheated the two phy controlers....... for any one another doesnt exist........ in receive i copy the packets in a dual port ram and distributed according to the mac address......broadcast and multicast are duplicaded.... under tests an374 dont loose packets in RX an TX...... because it has priority over uclinux packets........ try do it :) is very interesting ....... if you want i post the code...... cheers Franz wagner- Mark as New
