MySamba/Samba does NOT work with Vista - Problems again
Message #1 Posted by Eddie W. Shore on 25 Oct 2011, 10:29 p.m.

Today I tried to install build 1797 (or whatever it is) that was released today and first of all Samba-BA v2.10 once again failed to recognize my calculator and MySamba recognizes the COM but I keep getting "Failed to Connect" screen - no matter what COM I choose. I used another computer and that computer didn't even recognize the calculator even AFTER I installed the driver.

I am using EasySync ES-U-1001-R10 (US232R-10) - because that cord worked the last time. However it doesn't now and I'm back to having a dead 20b.

I am using Windows Vista. It doesn't matter how many times I download the driver.

I am putting a request for a cord that goes straight to USB cord without any need for a serial adapter because I can't imagine that I'm the only one with these problems.

----------------------------------- I should have enough saved up to buy an updated 15CE if HP gets the PSE thing fixed.

Marcus, when you have version 2 stabilized and officially released, I aim to buy an updated WP 34S from you.

Update: I downloaded the MySamba that was just released. Sadly, no success. I keep getting the Unable to Connect error.

Ed. The dead 20b is most probably no longer listening to the serial port due to flat batteries.

1. Only connect the cable while flashing!
2. Once in SAM-BA mode, remove the batteries if you do not succeed on the first try. SAM-BA will eat them quickly.

As for the USB cable you mentioned: Yesterday I built my own from an FTDI 3.3V-TTL cable and the original HP cable. I stripped the level shifter off the board inside the cable case and connected RX/TX/GND directly. In order to power the calculator from the cable, I added an external connector for a wall wart. Using the USB supply would need a 3V voltage regulator which I don't have. Maybe some kind soul redesigns the tiny board to contain a mini USB socket, an FTDI chip, and a voltage regulator, besides the two buttons, to make this a viable option for all of us.

Eddie,
I can tell you that I have gotten MySamBa (Marcus' version of the program available at Sourceforge) to work with Vista and the same USB-to-serial converter that you have, as described here. Did you right click on the MySamBa.exe file and tell it to run in XP compatibility mode?

I may have forgot to do that. I'll check. Thanks.

So I checked the Compatibility Mode, put new batteries, connected the calculator when the cord was flashing (which was all but a millisecond it seems) - STILL THE SAME RESULT: NO CONNECTION.

So I am back to the Samba CDC program - I click on COM 7 - and the program disappears! Then when I unplug the adapter I get this long error message:

error reading "file2d0e110": I/O error
  while executing
"read $fd 4"
  (procedure "TCL_Read_Int" line 6)
  invoked from within
"TCL_Read_Int $target(handle) $cidr_addr err_code"

  invoked from within
"foreach cidr_addr $addresses {
  #Check the processor ID
  set err_code 0
  set version_mask 0x0FF0..."
 invoked from within
"if {$target(board) != "no_board"} {

"source [file join $starkit::topdir lib/tkcon.tcl]"
  (file "C:/Program Files/ATMEL Corporation/SAM-BA
v2.10/sam-ba_cdc.exe/main.tcl" line 7)

This is the in the window "Error in startup script". Hopefully someone knows what is file is missing (if I am understanding this message correctly).

If I click on COM 3, Samba v2.10 will give me that "Old communication error".

I will seek help to get my 20b back to working (if it is possible) but as far as me using the cord to flash calculators is concerned - I'm done. It is too frustrating a process.

The sequence of events should be:
  1. Start MySamba and fill in the fields.
  2. Connect the cable.
  3. Reset the calculator.
  4. Turn on the calculator (you will not see anything). Hold down ON for a second or so.
  5. Click "Send File" in MySmBa.

If MySamba errors out immediately (no noticeable delay) you have a problem between MySamba and the Windows driver of your serial port. If it takes a second or longer to error out, the problem is between the communication endpoints such as a calculator not answering the packets from the PC.

Download and install "Free Serial Port Monitor". It will show you what is going on on the serial port. I used it to debug the communication between the emulator and the device but it should equally well tell you what is going on (or not) while flashing.

That's bad news. :-(

You are a miracle worker! I achieved success this morning and Version 2.2.1782 is on my 20b.

Thanks everyone for your help and your patience with me.

You make me curious: What did you change?

Holding down the ON button before clicking on download.

I have SAMBA 2.10 with my Vista (32 bit) machine. It installed 2 versions. The one with a "_cdc" tag indeed does NOT work. The one without the "_cdc" works fine with my FTDI USB-to-serial converter.

CDC assumes a working USB device implementation on the target. This is obviously not the case with an HP 20b or 30b.

SAM-BA is awfully slow compared to MySamba. Either Atmel has done a horrible job or Cyrille an extraordinary good one. I assume both is true. Think of 3 minutes versus 20 seconds to reflash the device. Why SAM-BA is so slow and why it is so picky with the execution mode or the serial port driver is beyond me.
