Support for NANO USB Programmer

Greetings everyone,

I'm a new member of flashrom mailing list, searching for info pertaining certain external programmer and corresponding 'flashrom' support. I noticed that the official list of supported programmers has not been updated for quite a while (January 2018), so I'd be interested to know if anyone succeeded to make it work - running 'flashrom' on Linux machine, in combination with this tiny programmer:

Product designation: "NANO USB Programmer"
Mfg: HS-TECH R.O.K, Korea
MPN: NANOUSB001
Site: http://shop3.nanobios.cafe24.com/article/download/7/8/?page=1

Programmer's core silicon:

Name: Cypress enCoRe II
Short description: Low Speed USB Peripheral Controller, with 8-bit M8C core.
Chip designation: CY7C63813-PXC
Ref.: https://www.cypress.com/products/encore-ii

USB ID: 04b4:3813
Name: NANO BIOS Programmer
Link: https://usb-ids.gowdy.us/read/UD/04b4/3813

WIN driver: cyusb3.inf (in case it's relevant);

----------------------------------------------------------------------------

I already contacted the guy, who runs the website mentioned above (shop3.nanobios.cafe24.com), and who also sells these programmers on eBay. He responded that in-the-house software, currently "NANO BIOS Programmer v1.1", is the only software that works with their Nano USB Programmer, but he promised to look into possibility, to "run an open platform software" for this programmer, as he elaborated in his response.

Since I have doubts that Windows based programming SW will be ported to Linux, at least not in a foreseeable time window, I would appreciate any useful information, as in - whether this programmer is supported by 'flashrom' project, what needs to be done to make it happen, which Linux distro you're using (in case it matters), etc.

Thank you in advance !

Kind regards,
Bostjan

Short follow-up to my initial post;

Windows driver corresponds to device, named »Cypress FX3 USB BootProgrammer Device« (as referred to on the drop-down menu in Windows Update Driver installation wizard). Perhaps not really a monumental news, but might add a helpful hint to someone.

Kind regards,
Bostjan

I received a response from a member of Cypress Development Community, that's not very promising, but still ...

"We don't have any linux drivers for Encore II which can be used with flashrom utility. Please check with Nano USB if they have any driver to communicate with the programmer on Linux. Best Regards, Sananya"

Given the obvious close relationship (at least to me it seems so), between Cypress FX3 and EncCore II families of USB devices (name of Windows driver for Nano USB programmer, device name...), and considering the ongoing development of Linux SDK for FX3 series devices, I was hoping for a bit more optimistic response, but I guess I was wrong. I still believe that Nano USB programmer, as well as Cypress EnCore II CY7C63813-PXC have a great potential for flashrom community, but the lack of Linux driver is a definitive setback.

Kind regards,
Bostjan
