Making the VS1000 bootloader file for SPI flash

I am using VS1000 from
Adafruit Audio FX Sound Board - WAV/OGG Trigger with 2MB Flash to develop the firmware reference to VS1000 Audio Module - VSIDE (VS1000AudioModule-072b-VSIDE). I can promming based on the solution from VS1000 audio module without problem. Now I want to promming back the original firmware back to the board, I only got the BIN firmware from here (2M110514.BIN), how to promming back the firmware from BIN file using VSIDE?

Other questions are related to making image file from VSIDE:
1. What are the different between "coff2allboot" and "coff2boot" executable file?
2. It seems VSIDE builded the COFF file out, is it the same as xxxx.spi file?
3. I am trying to use "coff2allboot -x 0x50 -d $(BUILDPATH)\$(TARGET) eeprom.img" to create the SPI image file, I can promming it back to VS1000 without problem (from the log), but it seems the firmware is not running, any problem to create SPI image like this?

Thanks!

1. coff2allboot is newer, and it supports more boot image formats (and also overlay linking for vs1000).
2. .coff is an object/executable format. You can convert it to SPI boot image using coff2allboot.
3. If the project is based on the VS1000 Audio Module, the solution consists of 4 separate programs. You create the boot image for each of them, then combine with combineimg. You then program the combined image into the SPI FLASH.

See http://www.vsdsp-forum.com/phpbb/viewto ... ?f=8&t=461 for more information.

VSIDE should have a prommer for previously prepared image. Copy the image to eeprom.img and use that version of the prommer.

Alternatively, you can use pcflash.exe, see http://www.vlsi.fi/en/support/software/vs1000tools.html .
