I also ohmed out the 8 to 16 pin header and found that it had the correct traces in place to interface directly with the 16 pin MX25L6445E chip and the CH341a ZIF socket. Cuando necesite más ayuda para encontrar los programador más populares, todo lo que necesita hacer es ordenar por pedidos. The lack of any voltage on MOSI and MISO leads me to belive the chip is broken internally, though it's strange that is still enumerates from the USB side. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. Unfortunately the bit in question in the FLASH chip's status register is non-volatile so quad SPI mode is 'sticky', as opposed to the sane alternative of making that bit volatile and having the host processor configure the chip appropriately for the application circuit on startup.

The latter are signs of a 'dry' (bad) joint, too much solder and either movement while it cooled, not enough heat or a lack of flux, maybe due to carrying * the solder to the joint on the bit so the flux core burnt off before it got there - Always apply the solder to the work, never to the bit (except after wiping it, the bit needs a tiny drop put on it for good heat transfer). I changed them to 100nF, added 10uF on the 5v input to the regulator and 100nF on the Daughterboard holding the SPI Flash (W25Q64J).I will upload a well commented version once I have added these comments for better reading and unstanding. AM)asrockuser Wrote: do you mean that what the software display is a real representation how to insert the bios chip into the programmer? Once everything is connected correctly, it’s time to configure your settings in Flashrom or whatever application you’re using for programming needs (e.

The “Size”, “Page”, and “SPI commands” will also auto-populate so you should not have to mess with them. I haven't looked into the CH341A enough to know whether ACT is supposed to go low when recognised by the host pc or later during some USB initialization perhaps before chip programming. AVR's are supported through a few programming apps for the hobbyist within limited support for the latest chips but then again there is MPlab for that in the meanwhile but at a cost in comparison. For those who don't know - the pins on the actual programmer are not numbered, the red line from the clip wires should be on the side and closest to the locker handle. Then no recover possible with the tool and no UUID, add the SN and the MAC, let this be a lesson to you.EXE - self installing archive with multiprotocol interface driver ( this one is for the programmer mode). which has English as the language, but it may have incompatibility with some chips, especially high-capacity memory. The drivers is a bit of an issue as not all the apps works through the same drivers, damn annoying but not to much of a hassle if you know which driver works best with each app. The connections were easy to make since everything has either pin markings, silkscreen prints, or some type of indicator to reference pin 1.

You can also use "Auto" button to program the chip which will verify the data after it was programed. If you are going to use it on other unknown hardware circuits containing low voltages components then be aware of the risks.programmer, in addition to the Vcc pin lift already discussed, you need to add a tiny DPDT switch with one pole switching Vcc between 3. Maybe these videos will make it clear that without the recommended mods how casual use without consideration for proper voltage levels to the target bios/memory chips could lead to a disaster. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item. Initially I was a bit reluctant, as I had of cause read about the need to also connect V3 (pin 9) with 3.
