Firmware updates and fixes for the new Directstream MK2

;it does not see usb drive. what should it be formated to?

I put both img and FPGA files in an old USB and follow the steps. FW was updated but 198 never showed up. It only shows 179.

FAT32 will work

Was “fpga1_198_Antero.bin” in the FPGA load menu when you used it?

Followed the instructions in section 2 of the .txt file and the update did its thing without any issues. The version screen shows 198-Antero for the FPGA and the music is flowing, so all is good. Thanks Ted.

I have tried all different formats
nothing shows up at all. going to get diff. thumb drive

And just in case - have you tried powering the Mk II off with the back switch, putting in the USB thumb and then turning the Mk II on? It only reads the directory of possible FPGA loads on power up (AFAIK)

yeah I did that and it worked. Thanks ted.

I did the same thing powering off and on, only 179 is in the menu; the 198 does not show up. I’ll try again later.

huh–i just tried to do the FW with the bin file
nthing happend when i turned the MK2 back on
no blinking lights etc

Did you follow the instructions in section 2 of the “How to Upgrade DSD MK2 firmware.txt” file?

With an FPGA load you pick a file in the load FPGA menu and it loads it, no blinking lights, etc. just a progress screen as it erases, loads and verifies the load. Then it prompts you for a reboot which is very quick.

The FPGA load menu is populated by reading the USB stick. If the USB stick isn’t working you can’t see 179 in the menu, if you see anything in the menu the USB stick is working and it will show you the FPGA files on your USB stick to pick from.

didnt see any of that.
Nor could i find 198 listed as an option
would assume its not reading the USB
thumb drive in EXFAT

have not had issues in past months with this drive and other updates

we dot unzip the .bin files correct
i was unable to anyway

exFAT did not work with earlier updates. I had no problem with FAT. Suggest you try that. Good luck!

thx–i use a MAC and dont see it as an option

I’m sorry, you said “didnt see any of that.” - any of what? If you are executing the instructions in section 2 of the “How to Upgrade DSD MK2 firmware.txt” from the download zip what step didn’t work/looked different than expected for you?

(Turning the Mk II off with the rear switch before putting the USB stick in and then turning it on after putting in the USB stick should reliably cause the Mk II to read your USB stick. - I need to suggest to PS Audio that this be explicit in the instructions.)

apologies
followed directions completely. Like other user I did not see 198 as a selection nor did I get blinking lights etc on the firmware update. Ive reformatted to FAT and am trying again

That’s probably the issue. PS Audio DACs have forever worked best (or only at all) with FAT32 formatted sticks.

My MK2 read the usb stick without powering off, the file didn’t show initially, deleted other non related files from the root folder, then the file was available for loading.
