New Windows OLS FPGA (& PIC firmware!) image loader...

January 09, 2011, 01:35:33 am

[-- Edit Jan 9th - Added source code], [-- Edit Jan 10th - Added github repository], [-- Edit Feb 6th - Added support for programming PIC firmware], [ -- Edit Feb 8th - Added flexibility for PIC firmware variations & now detects if OLS already in bootloader mode when starting.], [ -- Edit Feb 9th - Removed complaint about 8 byte difference in 2.6 firmware. Fixed stupid build problem with 2.01], [ -- Edit Mar 14th - Fixed Logic Sniffer detection for Windows Vista & 7.]
[ -- Edit May 14th, 2012 - Updated Flash ROM Table.]

Hi,
Since I've been busy on fpga tweaking I decided to make myself a
polished Windows GUI OLS loader.Â

I've attached screen images & a ZIP with the EXE.Â Supports HEX,
MCS (same as HEX), BIN (binary), -and- Xilinx native BIT files.

It can update either the FPGA ROM file, or the PIC firmware. Simply pick the
image file, and olswinloader handles the rest. No knobs, or extra checkbox
required!

Source is available below and on Github: https://github.com/ied/olswinloader

Enjoy!Â

Very nice! I really like the auto port detect, it is such a pain to go to the device manager every time to see what port is being used. Ill use this app for sure.

There are a couple new rom additions for the v1.04 boards that are not in svn yet, ill try to get them committed or post the data here.

Ols-loader was made by robots from pirate-loader made by pppd. There is no stated license, but i think we can ( and do) consider it gpl.

Let's make it GPL :-) I should probably patch the source to include the GPL statement and other stuff. (one day i will)

No problem. If it's ok, a short post here would probably be easier. I made some changes to the original code, to return error codes instead printing error messages.

Also, I've attached source now (in first message). It includes a revised ols_loader that uses the new plumbing if your interested.

Cheers!

Code: [Select]

const struct pump_flash_t PUMP_Flash[] = {
	{
		"x1fx24x00x00",
		264, // size of page
		2048, // number of pages
		"ATMEL AT45DB041D"
	},
	{
		"x1fx23x00x00",
		264, // size of page
		1024, // number of pages
		"ATMEL AT45DB021D"
	},
    {
		"xefx30x13x00",
		256, // size of page
		1024, // number of pages
		"WINBOND W25X40"
	},
    {
		"xefx30x12x00",
		256, // size of page
		1024, // number of pages
		"WINBOND W25X20"
	},
};

Thanks for the update. Here's the ROM struct.

Got it. Easy update. Quick question... Since the "WINBOND W25x40" is a 4MBit device , shouldn't it have 2048 pages?

Probably

The OLS only uses the first 2MBIT and I don;t think the app does anything with that value (beside range check?), so it shouldn't cause issues, but I updated it in the source anyways.

The loader is now updated with the latest flash rom support.

You should make it part of some Source tracking system, like git, svn .... It gets really annoying managing the source in forum :-)
I personally suggest git (github, gitorious, unless you have your own).

We'll that was fun...Â Never created a public repository before.Â First time for everything I guess.Â

You will appreciate it when it comes to patches :-)

I've updated my Windows GUI OLS loader to support programming PIC firmware. There are no extra knobs or buttons needed.

Just select an image file, and the loader knows where to put it. Small files for the PIC, big files for the FPGA.

Cudos to robots for discovering the trick to fast PIC updates. See first post for images & source code.

Enjoy!

This utility is ridiculously handy! I LOVE it!

I added a copy to the list of update utilities.

Glad you like it!

Unfortunately I just found it didn't like the new 2.6 PIC firmware. Doh. The firmware was 8 bytes too small, and the loader too hyper-sensitive. So I've added a little flexibility there. Now it complains, but will continue.

Also, the image loader now detects a Logic Sniffer in HID mode from the start. Just in case the Logic Sniffer hiccuped, or doesn't have valid firmware, etc...

I apologize to anyone snafu-ed by this. If you short the PGC/PGD pins & hit the reset button, you'll kick the OLS into bootloader mode. Remove the short & the 2.01 loader will see & update it then.

Careful, those last 8 bytes are the config words, we need to protect that page because the firmware ships without them, and there are both 20mhz and 16mhz crystal OLSes.
