[edit] Unable to boot or problem with filesystem
Workaround: Update the NGW firmware. See the upgrade firmware procedure
[edit] U-Boot fails to read from SD card [#5996]
Description: When loading a file (typically ngw_jffs2_root.img v1.0.2) from SD card with U-Boot, the read stops with an error after a few bytes.
Workaround: Load some other software to read the file (e.g. Linux)
[edit] Dataflash over SPI does not work with high speeds (33 MHz) [#5216]
Description: Trying to interface the dataflash on the NGW with the SPI at 33 MHz does not succeed in writing the data. The blocks seems to not be written. Erasing at 33 MHz is ok.
Steps to Reproduce:
1. Set the SPI max rating to 33 MHz (or 66 MHz which is the AT45DB642D max) 2. Erase the dataflash 3. Mount and put data on the dataflash 4. Unmount and mount again
Actual Results: The dataflash is empty after the second mount.
Expected Results: See that the dataflash containes the files that were copied in.
Workaround: Use only lower speed (20 MHz)
[edit] USB mass storage device incompatible with linux / samba
One can not use the NGW100 as a USB mass storage device and at the same time have the sd-card mounted in Linux (i.e. made available for Samba). This is due to the design of Linux' drivers.
The USB mass storage device driver accesses the device directly, and if Linux / Samba and USB both writes to the device, file system will get corrupt, most likely beyond repair.
[edit] File system corruption
A bug has been observed in the Linux firmware delivered with the Network Gateway kit rev C. The bug may cause corruption in the file system over time. When corruption has occurred, the kit will typically fail to boot, and output an error message on the terminal stating Verifying Checksum ... Bad Data CRC.
The problem arises with extended writing to the file system (e.g. log files). A temporary solution is to direct these files to memory. A kit firmware upgrade incorporating this is released on Atmel.no beta ware.
[edit] FTP Server fails
The FTP put commands fails with the following Error:
502-PORT/EPRT is disabled for security reasons.
502 Please use PASV/EPSV instead ("passive on")
ftp: bind: Address already in use
The fix for this problem can be found on the FTP daemon page
