Hi Seb, Not a solution, what I did in the past to analyse these kind of problems, is after the download with the bootloader, readout the entire flash and config with a ICSP (e.g. XWISP) and save the hex file, analyze the hex file in MPLAB by importing and using the building dissassembler. Albert

I've bought a FDTI USB-to-serial converter, and would like to use a bootloader. So far, using XWisp, I've been able to blink a LED, and use serial/echo. I programmed my chip with a Tinybootloader for 18F2550 (included TinyBld18F4550_20Mhz_115200.hex). When I upload the same sample using tiny, it reports the upload is ok, but then nothing happens (no blink). I did not forget to use -long-start this time... Any idea why it doesn't work ? Thanks Seb jalv24lbeta -long-start -s ../include/device 18f2550_blink.jal jal 2.4l-beta (compiled Jul 28 2009) generating p-code 0 errors, 0 warnings 9159 tokens, 86588 chars; 1883 lines; 2 files live variable analysis iterations: 1 generating PIC code pass 1 generating PIC code pass 2 writing result Code area: 93 of 16384 used Data area: 3 of 928 used Software stack available: 925 bytes Hardware stack depth 0 of 31 -- Sbastien Lelong http://www.sirloon.net http://sirbot.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jallib" group.
