I bought the Sparkfun's Uberboard a while back and I was trying to run the "Bootloader Tutorial" I followed all the instructions, got the FW.SFE file, but when the Uberboard resets it does not load the code. I got the following:
SparkFun USB Bootloader v1.1 Boot up
complete No USB Detected Failed
Reading Header opening filesystem
failed Root open "UART0 setup…ing
firmware…
The "Failed reading header" what does it means? help, anyone? :S

From the sparkfun website:
HOW TO USE THE BOOTLOADER INCLUDED ON YOUR BOARD ---
Make sure you add the following to the Makefile: change build: elf hex lss sym to build: elf hex lss sym FW.SFE
--- insert this --- FW.SFE: main.elf @echo @echo $(MSG_FLASH) $@ $(OBJCOPY) -O binary $< $@
--- after this block --- Create final output file (.bin) from ELF output file.
%.bin: %.elf @echo @echo $(MSG_FLASH) $@ $(OBJCOPY) -O $(FORMAT) $< $@
and in the common folder change the following text in the file: LPC2138-ROM.ld change ROM (rx) : ORIGIN = 0x00000000, LENGTH = 512k to ROM (rx) : ORIGIN = 0x00010000, LENGTH = 380k
Otherwise it will won't write the file. Since the bootloader is sitting at 0x00000000.
I burned a few hours and brain cells on these issues. So, I hope it helps you!
