Hi, guys
Can anyone send me a good quality photo of the back side of this board?

Very much so grateful !

[hassana]

is it possible to test code of FMD using proteus?
I want to use FT60E211 to measure pulse width range between 200us ~ 30ms
how to do it?

Hi

Here is attached FMD-Link V2.7 schematics and firmware (full and boot only).
Tested using STM32F103CBT6 and work well with FMDIDE 3.1.1.3
For FMDProgrammer need some older version, I have only 5.3.6.5 and this not support this "old" FMD-Link hardware.

I have FMD-Link v4.7 hardware in preparation, already hacked firmware and extracted boot, but waiting for FT32F072 ICs to arrive.
They (FMD) used "own made" ones version of F072, and this have different USB peripheral architecture than reglular STM32F072 (different registers addresses for entire USB peripheral).

P.S. If somebody have some older versions of FMDIDE and/or FMDProgrammer please share somehow. Thanks in advance.

Hi guys. Short question. I have Aliexpress motorcycle dashboard based on ft62f0g. Currently, i'm an arm\cortex guy and never dealt with PIC before. I do not want to go too deep right now and just wish to know is it possible to reset the chip to unlock it to be able to write and debug my own firmware using FMD tools?
Don't want to spend on FMD-Link if finally need to solder a new chip due to not being able to load and debug code in the original one.

Do you have a datasheet for it? It should be mentioned there, look for the UCFG registers. I have no experience with FT62F0G specifically, but AFAIK, the flash protection fuse can be reset by full chip erase.

Yes, i have one from the official site. Will take a closer look. Thanks for the tip.

Hello zulea1
For the FMDLink version, firmware 3in1 should be suitable.
But, it is necessary that pin C9 be float...

Hi, everyone.
I've also tryed to made simple and cheap solution for FMD MCU programming.
Instead of copying their hardware programmer, I just take its firmware, reverse it, and ported functions to CH341 hardware.
There is much differences for two big group of MCUs - Standart and Enhanced (termins from FMDIDE).
Both protocols tested: FT61F133A for Standart F-Series, and FT64F0A3 for Enhanced F-Series.


Not say that was easy, and want to thanks to this topic: to TS socram for great start information, to gashtaan for helpful posts, and to kkstun for his specific solution.

As addition hardware, I use handmade PIC-adapter (two pair of npn+pnp trasistors for VPP and VDD control, TxD and RxD pins respectively).
Of course, for FMD we need only VDD part (RxD high = VDD On).
Or, even VDD of MCU can be directly feed from RxD pin, if CH341 fed from 5V. It is not recommended, and can only feed single MCU (without board), but that was tested too.



Software not yet ready for public, but if someone has different MCUs and want to make some tests - write PM.

[DIMM-bl4]

is there a link for the programmer.

Sent in PM, please check.
But I don't see this message anywhere in my profile, maybe because of newbie at this forum... Solved.

[DIMM-bl4]

this PROM content is copied to somewhere else after every reset, so I guess it could be prone to glitching...

gashtaan, probably, you found it too? And stopped all further work with that MCUs because of it...
