Open Bench Logic Sniffer / minimalism
What is the minimum communication to the OBLS to get back data?

If I send 0x02 (^B) to /dev/ttyACM0 I get  1ALS
If I send 0x04 (^D) I get more verbose details
0x06 returns current logic state
But 0x01 (^A) does not seem to return anything.
So if I send some arbitary setup data first e.g.:

0x80 0x00 0x01 0x00 0x00  divide by 128
0x81 0x01 0x00 0x01 0x00 send 1 sample 4 bytes
0x82 0x00 0x00 0x00 0x00 clear flags

0x01 trigger

I would expect data back now, but got nothing.

Anybody see anything I am missing.
I was going to go through the java client source but it is massive.

Open Bench Logic Sniffer / 0.9.5 client error
Running 0.9.4 works fine but lacks some advanced triggers that I want to try.

If I connect to port with a comms program, e.g. cutecom, I get this with command 0x04

Code: [Select]
x01Open Logic Sniffer v1.01x00x023.07x00!x00x00`x00#x0bxebxc2x00@ Ax02x00

So permissions are o.k.
This is the java error .. it does not mean anything to me.

Open Bench Logic Sniffer / PIC firmware update fails
Hello
I wanted to use version 0.9.5 of the java client, but that does not work, therefore I wanted to upgrade the ols firmware.
Pump loader for linux is in hidden the winbin directory and does not state if it is 64 or not. :)

Code: [Select]
billy@aurora ~/local/ols-0308/OLS_Upgrader $ linbin/pump-loader-linux/pump-loader -p:/dev/ttyACM0 -status
PUMP loader
Opening serial port '/dev/ttyACM0' @ 921600 ... OK
Found PUMP HW: 0, FW: 0.0, Boot: 0
Error - unknown flash type (00 00 00 00)

I though then to update the PIC firmware, I have just received a V1.04 (with 16MHz xtal) from SEED.

Code: [Select]
aurora OLS_Upgrader # linbin64/fw_update -vid 0x4D8 -pid 0xFC90 -ver
fw_update Version: 0.2.0
U2IO BootLoader Version reading: DONE.
BootLoader Version: 0.2.2

aurora OLS_Upgrader # linbin64/fw_update -vid 0x4D8 -pid 0xFC90 -r -ox orig.hex
U2IO flash reading: DONE.
RESET Device

aurora OLS_Upgrader # linbin64/fw_update -vid 0x4D8 -pid 0xFC90 -e -w -ix PIC_firmware/OLSv1.firmware.v3.0.hex 
U2IO flash erasing: FAILED.
Device is not found.
Operation aborted.
aurora OLS_Upgrader # linbin64/fw_update -vid 0x4D8 -pid 0xFC90 -ver
fw_update Version: 0.2.0
U2IO BootLoader Version reading: FAILED.
Segmentation fault

No go there then!

After a reboot to clear USB problems
Code: [Select]
aurora OLS_Upgrader # linbin64/fw_update -vid 0x4D8 -pid 0xFC90 -ver
fw_update Version: 0.2.0
U2IO BootLoader Version reading: DONE.
BootLoader Version: 0.2.2

The ols still works but I would like to take advantage of the newer features, any thoughts?

I do have an ICD2.
