Simple programming for SPI series

**Yogus_X** · 06-10-2010

Hello,
I am trying to build a custom bios settings for Dx58so, now the problem is that I can not even test the program, though I can simulate it. What may be the reason for this? Any kind of information is appreciated. Thank you for your help in advance.

The scheme simplifies the hike up to 50-100% (depending on the cheek), the best option 74NS244. One is a flash and with flash cards for a couple of experiments? I guess this is correct and it has helped you.

But interestingly, a program that is attached to this simple programmer will support flash or other companies will be the ID code to identify and refuse to work with them, and will only work with proprietary ST? according to preliminary information from third-party flash does not work

Where have that is not supported? What writes softina reading? USB flash drive is detected properly, or not? What is the length of the wires? What is incidentally collected and verified whether the performance?

Slipped information that some are written in Flash correctly only to the reduced voltage, so he faced a similar situation. Winbond W25X40 sewed with errors at 3.2v. Dropped food to 2.8 (with power 74hc244) - sewn properly. About the length of the wire - better to be right on the connector to solder, made in a box on the connector socket on top of the drilled hole is inserted.

Also brought this device to Sleep-series but 74LS244. Maybe a problem with read-write in the pull-up resistor to 4.7k their (Authors will) advised to clean and I also collected without Winbond W25X80 sewn without problems.
