Re: CH341a SPI / I²C programmer
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.Leave a comment:

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...Leave a comment:

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

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 portLeave a comment:

Re: CH341a SPI / I²C programmer
Do I require any special program for that function or with any program such as telnet or putty?
Thank youLeave a comment:

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.Leave a comment:

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.Leave a comment:

Re: CH341a SPI / I²C programmer
bios connector??
ch341 is not jtag, it's spi/i2c
bios?? connector is either spi or lpcLeave a comment:

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.Leave a comment:

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.Leave a comment:

Re: CH341a SPI / I²C programmer
i read the bios - edit - erase and reflash againLeave a comment:

Re: CH341a SPI / I²C programmer
well you need to check the schematic, there may be something else linked to the connector.Leave a comment:

Re: CH341a SPI / I²C programmer
did you remove the chip first?
and did you save a backup?Leave a comment:

by what_1282105Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

I'm able to read and write the chip by selecting a winbond IC of the same size, but when verifying it fails at around 25 percent.
I've modded the ch341a to 3.3v.
Can I update the database to include the XMC 25QH256C? -
by sasalliHi to all!
i have ch341a programmer. iam trying to program MX25L6475EM2I-10G chip with 16mb file, bu the programmer software(v1.18) says ''FILE LENGHT, BEYOND RANGE OR IT WILL BE IGNORED''. What should i do? Thanks! -
by fanchiottiHello everyone,
I have a lenovo ideapad s145-api and after a bad bios update, it's bricked.
I bought a ch341a programmer, installed all the drivers, it's working as expected, except when i put the clamp on the bios chip the power led goes dim and the win 10 emits the "device is disconnected" sound.
NeoProgrammer doesnt detect the chip at all...
The laptop battery is disconnected as is the bios battery.
I believe the bios chip is this one: https://www.winbond.com/hq/product/c...ory/serial-nor... - Loading...
