NP-41 Emulator (may be)

[Sylvain Cote]

Hello Chris,

Sorry for not coming back sooner.

First, I do not have a Windows PC, I use a MacBook Pro running OSX v10.11 64 bits with Parallels v11 and a Windows 7 32 bits in a VM.
I have spent the last 2 hours trying unsuccessfully to update the unit and now I have fried my unit. 8-(
I was working on a antistatic mat with a grounded bracelet at all time

This is what I did ...
a) I have downloaded and installed the mspdebug-0.23-win32-signed.zip software
b) I have downloaded your firmwares
c) I have tried to use the command -> mspdebug rf2500 "prog np41.hex" but the software is not seeing the MSP430 through the USB port
d) mspdebug --usb-list return nothing
e) I then registered myself on TI website and downloaded the dev kit (msp430.dll_developer_package_rev_3.07.000.012.zip)
f) I then installed the VCP drivers and Windows now sees the MSP430 unit as COM7
g) mspdebug --usb-list still return nothing (as expected)
h) mspdebug rf2500 "prog np41.hex" still not working (as expected)
i) I then downloaded and installed the "Realterm_2.0.0.70_Signed_Wrapper_setup.exe" software
j) started RealTerm and he sees the COM7 with 9600,n,8,1
k) I have tried to go into the bootloader as instructed and tried multiple things (no battery)
-> physically disconnect/reconnect the USB cable with user key pressed (several times, never worked)
-> virtually disconnect/reconnect the USB cable with user key pressed (several times, never worked)
-> physically disconnect/reconnect the 6 pins cable from the calculator (once, this is what killed the unit)
L) Then I tried to insert a new battery but there is no response anymore

That was short!!

Best regards,

Sylvain
