Dear William Scott, Bill.

I really appreciate to you for your support.

I am using SD card file system in OMEGA2+ to extent storage.

Can I use both SD card file system and swap file extension in SD card?

I will really thank you if I can be given the method.

It is very important job for me.

The following is my setup procedure to use SD card file system.

• File system extension procedure of OMEGA

1. install file system program.
   opkg update
   opkg install e2fsprogs

2. unmount SD card.
   umount /tmp/mounts/SD-P1

3. format SD card
   mkfs.ext4 /dev/mmcblk0p1

4. copy overlay
   mkdir /mnt/mmcblk0p1

mount /dev/mmcblk0pl /mnt/
mount /dev/mmcblk0pl /mnt/ ; tar -C /overlay -cvf - . | tar -C /mnt/ -xf - ; umount /mnt/

1. auto-mount of overlay when start up.
   opkg update
   opkg install block-mount
   block detect > /etc/config/fstab

   vi /etc/config/fstab
   Find "option target '/mnt/mmcblk0p1'" and replace it with "option target '/overlay'"
   // Find "option enabled '0'" and replace it with "option enabled '1'"
   reboot

2. Check SD card file system.
   df -h

Thank you very much.

Dear William Scott, Bill.

I really appreciate to you for your support.

I will follow your instructions.

Thank you very much.

Dear William Scott.

I really appreciate to you for your answer.

My OMEGA 2+ system halts after about 2 days after running program.

I will check the memory and disk space.

I think the memory problem can be solved because OpenWRT linux uses virtual memory (memory using disk).

Can I enlarge the virtual memory of OMEGA 2+?

If I can do it, would you tell me how to enlarge the memory?

Thank you very much.

Dear JP Norair.

Thank you very much for your precious suggestion.

I will try it.

Dear William Scott, Bill.

Thank you very much.

I can send the message after stoppage of receipt. The write function is executed normally.
Though read function is executed normally, my program can't receive any message.

I made LED message receive/transmit checker at the other MCU.

The MCU seems not to send/receive message.

This serial port hang happens after 2~3 days from program running.

Once this happens, the serial port does not work even though I re-run the program.

If I reboot or power down/up agin, the serial port works.

Thank you very much.

Dear William Scott, Bill.

My C program and java application(using nodejs node) is run.

The following is java server.

1495 root 43172 S /usr/bin/node /root/www1/build/serverTest.js

The java server run child en.app.js java script.

The hang is different whenever I run the program.

This time, the serial port communication does not work even though it seems to send the message.

The counter part MCU does not send/receive messages through serial port.

Thank you very much.

Dear William Scott, Bill.

The program stops operation and the log output screen is freezed.

I am using socket communication with java program, UART communication, sleep function, and 3 threads.

I put printf at every line of my program.

The program stoped between printf function.

Thank you very much.

I am using OMEGA2P and firmware version : Ω-ware 0.2.2 b202.

My program stops after a few hours (such as 5 hours).

Both MPPT1 and serverTest.js programs' STAT is in S state.

STAT S : interruptible sleep (waiting for an event to complete).

Almost all process state is in S state.

How can I solve this problem?

The programs should not be stopped.

It is very important for me.

I will appreciate if I can be given answer or solution.

Thank you very much.

Would you try this.

opkg install nodejs
opkg install npm

If this does not works, try this.

opkg install node-npm

Dear William Scott, Bill.

Thank you very much.

I am testing that messages are still being sent after the stoppage of receiptnow.

I made LED message receive/transmit checker at the other MCU.

Because this happens after 2~3 days from program running, It takes some time.

Thank you very much.
