I've never tried any Linux version of SAM-BA, so this may not apply at all, however the older Windows version of SAM-BA was intended for use with Serial cables (as was used for HP-20/30/WP-34S) and is totally incompatible with the new USB cable. Possibly, the same is true with the version you're using, I just don't know, though I too would probably assume Windows 3.18 was functionally compatible with the Linux 3.18 version.

The 3.x versions won't work at all, I think, not even on Windows, because they don't support the SAM4L. But I was trying to get the Linux version of SAM-BA 2.18 to work. It's quite old, and I was trying to get it to work on an up-to-date Linux distro, so that probably has something to do with it. It might work better on a few years old distro.

Anyway, the problem I'm having is that I run ./sam-ba_64, select the USB CDC COM port, "/dev/ttyACM0" (which is the one created when the HP-15C CE was put into firmware update mode) in the dialog box, select the board type "sam4l-ek[not factory programmed]", and press the "Connect" button… and then it locks up.

The output on the terminal I run ./sam-ba_64 from is as follows:

Code:


-I- Waiting ...
-I- TCL platform : Linux
-I- SAM-BA CDC 2.18  on : linux
-I- Connection : /dev/ttyACM0 (target(comType) = 0)

-I- Traces Level : 4

-I- Loading applet applet-flash-sam4l4.bin at address 0x20002000

EDIT:

I've only managed to trace the problem as far as running the chip's "init" applet command (0x00) in this part of the GENERIC::Run function in "tcl_lib/common/generic.tcl" (called from GENERIC::Init):

Code:


    if {[regexp "linux" $samba_os]} {
         set result $cmd
        while {$result != [expr ~($cmd)]} {
            if {[catch {set result [TCL_Read_Int $target(handle) $appletCmdAddr]} dummy_err] } {
                error "Error polling the end of applet execution"
            }
        }

It doesn't seem to return from that "TCL_Read_Int" command.
