Title: Problem Loading Hh Bl - Reset Not Recognised
Post by: d2a on August 09, 2008, 10:38:17 am

in the past i've managed to install previous versions of the bootloader, but always reverted to the siemens one because of the instability of early linux builds. wanted to try the new build, so followed instructions: erased flash memory via terminal. then closed terminal and ran serload blupdater.img. prompted to reset, but no response from serload when i do. tried all combinations of reset plus button and nothing seems to register. now just get the tartan screen obviously.

simpad connected to windows xp machine, bootloader is siemens 2.5.3, old OS was CE 4.1

any ideas?

This sounds like you have forgotten to change the serial speed settings for bootldr.
The settings for bootldr are:
"As connection settings you should use 115200 baud 8 databits no parity 1 stopbit (115200 8N1), no hardware and no software flow control."

hmm - well, that isn't strictly accurate. in order to view the monitor menu and therefore erase flash, the terminal settings need to be 38400 8N1

this is the output of the terminal using those settings:

i enter y to erase flash which then shows the ascii progress bar. when this completes i disconnect the terminal, and try the serload blupdater.img in a dos prompt, which then displays the prompt to reset. however when i reset, there is no response and the fact i've reset the device is not recognised.

is there a setting in the bios that might effect this? i will try using a different (linux) box

a ha - tried using my old linux box and it worked straight off. must be something wrong with my XP box. serial download in progress - fingers crossed it all works out. thanks for the reply anyway.
