LPC2138 Bootloader - thos_fernando - Dec 8 3:57:58 2007
Hello ,
I was testing out H-JTAG on my LPC2138 system, and loaded one of my
working hex files using H-JTAG.
I think I must have over written the Philips bootloader in the
process.Now I cannot flash using the WinARM or philips ISP tool.
Is it possible to get the bootloader going again ?
I read one thread of klemen_dovrtel on this issue which ended abruptly.
Are the bootimage files uploaded by Jayasooriah same as a bootloader ?
" Twentyone " had some bootloader files on his H-JTAG site , but I was
not able to figure out how to use them.
Any support would be appreciated.
Cheers
Thomas

Hi Dave,
Thanks for that.There was a problem in the ISP part of my circuit.
No trashing of the bootloader as you figured out
Thanks again.

That's a masked ROM, right?
