Open Bench Logic Sniffer / Re: Can't update OLS
I tried connecting the ols to a windows pc. I could not manage to get the default upgrade tool to work (or didn't bother), but I used a program called ols_winloader. At first it failed to program the FPGA because a pull-ups selftest failed (Defective unit?), but managed to program after I disabled the selftests.

After failing to get the status from ols-loader on the linux laptop the device again refused to boot into normal mode, and had to be once again programmed on the windows pc.

Now it usually works on the linux laptop, but atleast the "get metadata" button seems to randomly fail with about 10% chance of it printing "null". Sometimes it seems to get stuck in this non-working mode and a replugging helps...

Open Bench Logic Sniffer / Re: Can't update OLS
It seems that by replugging the device I am able to atleast get the firmware updated:

Code: [Select]
[root@acer2 OLS_Upgrader]# linbin/ols-loader -p:/dev/ttyACM0

Found OLS HW: 1, FW: 3.0, Boot: 2
Found flash: WINBOND W25X40

However I still can't get the bitstream to upload...

At first is starts ok:

The board is v1.04 and I have programmed the PIC with svn trunk/PIC-firmware-dumps/PIC-firmware-dumps/OLSv1-DUMP-FW21BL2-16MHz.hex with a PICKIT3 after I screwed the bootloader up.

Any ideas?

Open Bench Logic Sniffer / Re: Rescue bootloader with PICKIT 3
Ok, I managed to fix it.

For whatever reason flashing the hex from OLSv1-bootloader-v2-16MHz.zip did not leave the bootloader in a working state(wrong version, wrong configuration, ...?). I was thinking about compiling the bootloader from source so I could run it in debug mode in MPLAB to see if it is even running. In the SVN if found a bunch of dumps in /trunk/PIC-firmware-dumps/. I chose the lates 16MHz version, and it actually worked.

I am glad I didn't brick my new owls the day I received it without having a chance to really even get it to work. Also now I know how to recover the bootloader just in case I manage to break it again :)

Open Bench Logic Sniffer / [SOLVED] Rescue bootloader with PICKIT 3
While trying to get both the firmware and bitstream to successfully update, I think I broke the bootloader (can't get to update mode). I tried to program the hex file in OLSv1-bootloader-v2-16MHz.zip from the thread linked to in the bootloader rescue thread, but it still doesn't go to update mode.

Pickit 3 successfully programs the chip and also verifies it ok, but I am not getting any kind of USB insertion message in dmesg and the ACT led does not get lit, even if I power up with the UPDATE button pressed down. What am I doing wrong with reflashing the bootloader?

EDIT: Are the configuration bits included in the bootloader .hex file, or do I have to set them up manually? If so that might well be my problem
note to self: configuration bits are on page 417
