MSI Eclipse MS-7520 Ver. 1.1

I was looking on www.macronix.com at their selection helper. MX 25L (means 3V, serial Flash), 32 (means 32MB density), 05 (STDsingle I/O), O (this letter is the generation of the chip - they showed an E), M (package = SOP), I (industrial tem range -40C to 85C), - 12 (85/MHz/86MHz), G (RoHS compliant). I believe this is the chip I have but will continue to look for a better magnifier.
 
MX 25L (3V, serial Flash), 3205D (32Mb), M2 (200 mil 80SOP), I (industrial temp range -40 to 85C), -12 (86MHz) G (lead free) . This is my best guess. I think we need to ask for this chip to be added.
 
Pin 1 = CS# _________Pin 8 = VCC
Pin 2 = SO/SIO1 ______Pin 7 = HOLD#
Pin 3 = WP#/ACC ____Pin 6 = SCLK
Pin 4 = GND ________Pin 5 = SI/SIO0
 
Embedded sent me an e-mail and said that that chip is the same as the 320 listed.
 
The MX25L320 is listed in the verified to work list.
I take it when you connect your BCUSB to the board that you have no power connected to the board ? ( as the only power source should be from the BCUSB)
Additionally you could maybe try using a different power source to the VCC rather than the BCUSB VCC point to see if that makes any differance.

Last resort is to bypass the JSP1 header and connect directly to the chip itself.
 
Correct. I have no power to the mother board. I was hopeing that the 3205D was different than the 320 listed but I guess it isn't. Do you solder to the pins on the flash chip or do you have some good ideas for contact connections?
 
I would personally just solder direct onto the chip itself , there are clips available but i find them unreliable.
 
I will give it a try on Monday. My wife has assigned me alot of projects for the weekend. I will go to work and get some rest and time to work on it.
 
The developer has passed on a image of how the connections should be

Note the extra VCC and GND has not been implemented yet , that will be in the next SPI firmware release. Basically our previous connections are exactly the same , hopefully we may have better results with the second VCC connection being added.

As soon as the firmware is released i will post it here for you to try.
 
I was given the opportunity to send my board to him for evaluation. I am hopeing that this means he had success. I did get an e-mail from Embedded Computers saying he would look at it (last night) and mail it out today. I will let you know what happened.
 
Yes, I believe it is but I can't really say until I see a whole picture or at least more of it. The timing and the fact that he said he was going to do it last night, would lead me to believe it is.
 
That is the correct connection , certain members have had issues not being able to detect the flash though , seems to be trial and error , as i do not possess any of these boards it is hard for me to find a straigh forward connection.
