<html>Hi Stefan,<br /><br /> Thank you for the clarification.<br /><br />I bought one of these:<br />http://www.ebay.com/itm/1158312-1-8V-ADAPTER-FOR-IPHONE-OR-MOTHERBOARD-SPI-FLASH-SOP8-DIP8-W25-MX25-USE/253102266601?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649<br /><br />Which is based on an AMS1117 regulator, coupled with a <h3 class="r" style="font-size: 18px; margin: 0px; padding: 0px; overflow: hidden; text-overflow: ellipsis; white-space: nowrap; color: rgb(34, 34, 34); font-family: arial, sans-serif;"><a data-href="" ping="https://www.google.no/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=0ahUKEwi_vsKAqdHWAhUiApoKHcU5Aq4QFgg0MAI&url=http%3A%2F%2Fbiakom.com%2Fpdf%2F74ALVC164245_NXP.pdf&usg=AOvVaw0FuGBs3E7yO5zl9C5Sw1XO" style="color: rgb(102, 0, 153); cursor: pointer;" href="http://biakom.com/pdf/74ALVC164245_NXP.pdf">ALVC164245 16-bit dual supply translating transceiver</a></h3><br />During the weekend, my new chips arrived, so I tried again, with the original setup: <br /><br />CH341a programmer -> 1.8V adapter -> test clip with original ribbon cable clipped to one of the new chips.<br /><br /> The flash procedure worked and verified flawlessly, so there is either some interference from trying to flash the chip on board, or the original chip is damaged.<br /><br />I'm sending the flashed chips to someone with better sioldering skills than me.<br /><br />Best regards<br /><br />Marius<br />On Monday, October 2, 2017 00:43 CEST, Stefan Tauner <stefan.tauner@gmx.at> wrote:<br /> <blockquote type="cite" cite="0MI8iw-1e2ci80ncM-003wHJ@mail.gmx.com">On Fri, 22 Sep 2017 12:36:44 +0200<br />"Marius Schrecker" <marius.schrecker@lyse.net> wrote:<br /><br />> I get (randomly):<br />> Found Winbond flash chip "unknown Winbond (ex Nexcom) SPI chip" (0 kB, SPI) on ch341a_spi.<br />> Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ch341a_spi.<br />> Found Winbond flash chip "W25Q64.W" (8192 kB, SPI) on ch341a_spi.<br />><br />> Finding the correct chip or not seems to have little or nothing to do with the physical contact to the chip.<br />> […]<br />> Again, the hex codes for the failures seem pretty random and are different each time I try the command.<br /><br />Hi Marius,<br /><br />it is indeed random, because you apparently pick up lots of noise.<br />Please see https://flashrom.org/Common_problems and<br />https://www.flashrom.org/ISP<br />Which voltage translator/adapter are you using?<br /><br />--<br />Kind regards/Mit freundlichen Grüßen, Stefan Tauner</blockquote><br /><br /><br /> </html>
