New "Artery" Goteks : Current HxC firmware support status

Post by Jeff »

Since March/April 2021 we can see some new Gotek variants on the market

Due to the electronic components shortage, these new Gotek revisions use different MCUs.
The STMicroelectronics STM32F105 MCU was replaced by Artery MCUs : AT32F415RCT7, AT32F415CBT7,...

These MCUs are "mostly" compatible with the previously used STM part but there is an important difference : The RAM size.
While the STM32F105 offers 64KB of RAM, these Artery parts have only 32KB of RAM.

Others points :


- The AT32F415RCT7 is a 64 pins device. This Gotek PCB version and the pins assignment are the same as the STM version.

- The AT32F415CBT7 is a 48 pins device. Some headers was removed and the pins assignment is different.

All of these points imply changes in the firmware :

-> Reduce several memory buffers/cache to fit the RAM usage into the 32KB available on these parts.

-> Remap some pins for the 48 pins MCU version.

Current HxC firmware Artery Gotek support status :

- The bootloader was updated this week to support all the 3 Gotek variants : STM32F105RBT6, AT32F415RCT7,AT32F415CBT7.

- The server was updated this week to support all the 3 Gotek variants :
The bootloader can installed on all these Gotek using the normal online procedure : https://hxc2001.com/docs/gotek-floppy-e ... ation.html

- An AT32F415RCT7 alpha version/test firmware is already available in the firmwares archive.

- The AT32F415CBT7 version is in development. It should be available in the next days. EDIT 12 April : DONE !

The future developments will be focused on the merging of all these firmwares variants.

The documentation has been updated / completed about the flash methods.
All previously available ways to program the Goteks still available with the Artery Goteks.

The Artery USB cable method uses a different software, but the process still mostly the same.

Does the Artery chip support the OLED screen?

I'm disappointed to buy my first floopy disk emulator (Gotek) and I see it has an Artery chip inside.

Does the Artery chip have any limitations in the firmware (so far) versus the STM32 version?

Yes OLED / Rotary / Extra button mods are working.

I still need to test the OSD (On screen display) ( and i expect to have some issues with these chips, but i already have some solutions fix this - need to implement the changes and test them)

The difference with the STM32 Gotek is that you will have continuous USB Stick accesses : There is no enough RAM space to store a full track in the RAM cache. A possible workaround is to use the motor-on signal to stop the USB read accesses when the machine doesn't read the disk. Similar issue with the write operations : The write size are shorter, this reduce the write speed. On STM32 Gotek, the firmware can write both sides of a cylinder in one USB stick operation. This is very fast. This is not possible anymore with the 32KB Artery Gotek. Multiple write operations need to be done to write the tracks. You may have some issues with format operations (and machines writing a full track to change a single sector) if the USB stick write latency is too long ... Since a full track doesn't fit in the RAM, the firmware need to write the track to the stick during the track change... The USB stick write latency is critical at this point. But you shouldn't have this issue with the classical sector write operation used to save a file anyway.

Anyway i am slowly improving the firmware to fix/workaround the remaining features impacted by this design change but the main usages scenarios are already covered by the current firmware version.

Jeff,

I've just purchased the HxC firmware. Thanks again for all of the help!

Does the Artery drive firmware support the Kryoflux / HFE flux formats?

That's really interesting that Gotek is selling drives with the OLED an rotary dial!

Do you know of any place selling the new revision?

Right now i don't think that this model is available, but you can expect to find these new Gotek with the OLED / Rotary on Alibaba/ebay in some weeks.

That looks really nice, but I'm still not a big fan of the large rotary encoder.

Has anybody used smaller encoders or other alternatives? (maybe just adding a third button for eject?)

I am not too. These rotary can be "dangerous" with some usages since images can be changed by accident very easily.

How did you load the HxC software onto your unit? I've also paid for the HxC firmware but I can't work out how to get the boot loader flash onto my device. Do you have a really good set of instructions I can follow?
