Hello,
Lately I am having problems communicating with the handyboard after it
is reset.
I can download the pcode_hb.s19 file using hbdl.exe downloader.
When the Handyboard is reset by toggling the power switch, the following
is observed.
1st symptom : No welcome message on screen
Running ic.exe after the reset causes something to be written to the
port as indicated by the RS-232 minitester, but nothing is returned from
the Handyboard side.
2nd symptom: <Following log>
Attempting to link to board on port com2
Synchronizing with board
Board disconnected or not responding, retrying
<infinite loop of above statement>
I have checked the Memory Power and it appears to be constant at 5.5V.
I have not checked it with an oscilloscope to see if there are any
spikes in the memory power.
I would appreciate comments in solving this problem.
Thank you,
Tejesh
