Programming chip 25LB64CSIG

[ut-norm]

Greetings to all. I need to flash the bios of an ASUS x509M. I have two CH341A and EZP 2019+ programmers that do not recognize the chip which is: Gigadevice 25LB64CSIG (I have the adapter for 1.8 v.). How could I do? Can I use another programmer or perhaps an equivalent chip?

It is 1v8 version. See if this helps:

Thanks mon2 I found the solution by reading the post.I programmed the chip with the CH 341A but without the 1.8v adapter.It didn't work with EZP 2019.The CH 341A recognized the chip as GD25Q64 powered at 2.98 v. voltage measured on pins 4 and 8. The PC with the new bios began to charge the battery and started up. Thanks again

Hi,
I would like to thank you.
This was usefull for me.

ut-norm If using CH341a and converter 1.8v, does it detect the chip? I afraid without using converter it would be burn the chip. May i know which ch341a programmer version you be using to reprogram the chip?

It's easier to flash the IC chip without having to remove it from the mainboard and I've tested it using the ch341a black edition

I am using linux flashrom and I have this problem.

sudo flashrom --programmer ch341a_spi --read read01.bin

flashrom unknown on Linux 6.8.0-51-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found GigaDevice flash chip "GD25LQ64(B)" (8192 kB, SPI) on ch341a_spi.

To me, sounds like a Linux related local issue since the LIBUSB transfers are not being processed. Test with another distribution.

I have updated Linux Mint 22 and I tried different USB ports.
Tomorrow I will try a completely different PC.
The log shows that the programmer identified the chip, but could not read the data.
