Difference: NS-DVxGPort (r9 vs. r8)
This page is for gathering information for a Rockbox port to Insignia NS-DV player. It should be noted that the iRiver X20 is nearly identical and is able to run the NS-DV firmware with slight modification (http://forums.rockbox.org/index.php?topic=9668.msg123507#msg123507 see here)
The following photos are from an NS-DV2GC. The NS-DV2G is physically identical:
Removing the NAND chip daughter board will force the device into USB Boot mode. The board is found directly under the NS-DVxG printing on the back of the player. To remove it, do the following:
Now that the player is in boot mode, drivers are needed. I (Edwin) had success using tcctool in windows but not FreeBSD?. So, you can download the tcctool and driver package here:
You'll need to edit the tcc.inf file to include the TCC8200 as of this writing. I'll try and find out who to bother about changing that. Under devices, you need to change the inf file to read:
You can leave any other defined devices in that list if you like.
Now, simply plug in your player and manually install the tcc driver. Tell the driver wizard where the inf file is, and it should do the rest.
You should now be able to use tcctool to boot firmware files.
The firmware flash procedure for the NS-DVxG consists of copying a firmware file (*.rom) to the root directory of the device, then disconnecting it from USB. Once this is done, I assume the current firmware verifies the checksum and copies the new firmware to the protected area of Flash memory before deleting the file. Insignia supplies firmware updater and downgrader installers which copy the ROM file to the device. This means if the device is in mass storage mode (plug in the device while it is turned off and the hold switch is on) an end user can can copy the file before unplugging the device and store it for later use.
