Re: CH341a SPI / I²C programmer

What is the latest free working version that can be found in the programmer's software

Hi. Spork Schivago

Use Windows 10. Now download the driver and software that corresponds to that programmer. I have already successfully recorded several CHIP BIOS.

But I wanted to evaluate serial connections to connect to ADSL modems.

Thank you.

Re: CH341a SPI / I²C programmer

If you're in Windows, you'll more than likely need drivers for that programmer and in Linux, you'd need the proper module(s) before you can start using it. If you tell me the OS, I can help find drivers so the software you run to program the chips can properly communicate with that programming device...

Re: CH341a SPI / I²C programmer

Thank you

I'll do the tests, then I'll tell you.

Greetings.

Re: CH341a SPI / I²C programmer

on Linux it will be ttyUSB0, on windows you may need to configure the serial driver - but i will show as a com port

Re: CH341a SPI / I²C programmer

Do I require any special program for that function or with any program such as telnet or putty?

Thank you

Re: CH341a SPI / I²C programmer

yes, the programmer can act as a 5v or 3.3v serial port to talk to other stuff like routers or ST microcontrollers etc.

the jumper across pins 1&2 configure it as a programmer - move it to pins 2&3 to act as a serial interface.

Re: CH341a SPI / I²C programmer

Hi, STJ.

I explain myself better

When I referred to the (BIOS Connector), I wanted to tell the connector zero insertion force, highlighted in blue in the photo that I attached.

On the connectors that are next, I would like to know if they can be used to program modem or communicate via serial with other devices.

Since in red, I see a serial connection I assume RS232 to TLL.

and highlighted in yellow, I see MOSI / MISO connections. which corresponds to the one obtained in the router / Modem ADSL cards for example.

I wanted to know if you can program or communicate with these devices using this programmer as an interface.

Re: CH341a SPI / I²C programmer

bios connector??

ch341 is not jtag, it's spi/i2c

bios?? connector is either spi or lpc

Re: CH341a SPI / I²C programmer

Hi all.

I have the black edition of the programmer, I would like to know if they have used it as a JTAG interface. To program for example Modem ADSL, WIFI Router.

If so, as they have done with that software they can make use of the pins that are next to the BIOS connector.

Thank you.

Re: CH341a SPI / I²C programmer

macbooks from 2012 wont be the same as 2017
i prefer to lift chips for flashing - it eliminates any chance of error.

thanks so much. i'll try

Re: CH341a SPI / I²C programmer

well you need to check the schematic, there may be something else linked to the connector.

i tried with old main board, macbook pro 2012 it stilled working. i dont think it have problem with the connector

imho it's bit odd when someone tries to erase the bios hopping to clear the password...

i read the bios - edit - erase and reflash again

Re: CH341a SPI / I²C programmer

did you remove the chip first?
and did you save a backup?

i didn't remove the chip, i had tool just plug in the connector. i had backup file

Re: CH341a SPI / I²C programmer

Hello. i used CH341A Mini Programmer to clear bios password for macbook pro 2017. it detectd the chip, read ok but when i tried to blank, it said 'the chip are not null' and now it broke the bios chip, laptop not turn on. Can u help me to fix the problem ? thanks so much
