   Hello,            As a user. Can you, please, post some pictures of your work?

I have only tried ISP because the chip is a SMD located on an airbag unit.

   Hello,            If the problem is created by cable length, and excessive 'parasite' capacities,
reducing speed of communication, may help, or not. Having all cables, with similar
length to avoid protocol timing corruption. Then i recommend use some adapters
that are like 4pcs for Sop8 Soic8 chip download burn write probe spring needle flash eeprom chip burner cable Sop8 Soic8 chip - AliExpress 13
or 1PCS TSSOP8 MSOP8 PCB chip burning test fixture probe download programming cable - AliExpress 13
chip case dependent, anyway , some of those adapters do have excessive cable length, but can have easily
modified. Also, the xgecu program, allow for T48-T56-T76 programmers  that initial surge
current to be changed, to accommodate 'in circuit' use, it may fail first try, but almost work
second time, with voltages stable.

Hope it helps

Thanks for the suggestion about the cable length. The current cable length is more like 30-40 cm.

Hello, voltage can be stable for M95640W, from 2.5 to 5.5v, but 'stable'
as per datasheet, but in circuit with other ICs can be higher or lower....

You can see that they recommend lower then 25cm... For T76, T56 or T48, and recommendations
for clock lines....

You show, in the proto board the IC in an adapter that may fit the programmer socket directly,
then length cables at the lowest :-)

If any software change that may help you, hopefully Admin read this, and implement.

Sorry,I haven't specified that I am using a T48.
I am following the guide for the clock. The M95640 ...

   Hello,            If not successful, also try to reduce the speed to half at bottom (others) , or also a speed increase, as you have an analyzer, trustful information will arrive, hopefully,
to developers, in case a software adjustment maybe, also, needed.
Thank you to share with us your work :)

Hello,
         In the past, the better and faster way to contact way to contact them, the place was here, in one of the threads.
As i know, Admin, appear to be so busy, that i almost not seen here often, or it's reading only the forum...at that time
updates were released almost every month, now we never know when they will...
Xgecu show 532007590@QQ.com as a support contact in it's page where you download the software.
I know there exist a Telegram channel with at least, many users, but i never used it .
If you buy your programmer in a shop that is a 'top agent', like lrf XGecu T48 Programmer Support NAND/EMMC/MCU/ISP
contacting them will speed up the process.
Please, tell us know here, any improvement you may get in the process, and what you have done,if you ever tried to program in a complete new IC ( some ICs have OTP registers, some have more
then a layer, software and hardware protections, etc )

Hope it helps!
