Hello, I appreciate any response to the following query...
I am developing a project which utilizes u-boot. I started from an Atheros source package which contains a modified u-boot for their AP83 reference design. This reference design has an SST flash chip (SST39VF6401 - http://www.sst.com/products.xhtml/parallel_flash/39/x16/SST39VF6401). This all works well. My OEM partner for the project has developed a Prototype A design, which (in principle) is based on AP83. However, the flash chip is different. This design has an MXIC flash chip (MX25L12805D - http://www.macronix.com/QuickPlace/hq/PageLibrary4825744A00264C7F.nsf/h_ Index/E2C69FC9EFF9292F4825744A0029FE02/?OpenDocument&PartNo=MX25L12805D) I am able to boot the board with this u-boot; however I can not access the flash chip properly. The chip is not identified or addressed properly. I don't have any starting source that I can find for this particular flash chip. I have tried modifying the #defines in flash.c to no avail. I have also tried using various source files (flash.c/h) which I was able to find under our u-boot source tree, as well as 3rd party published source code. At this stage, I'm under the impression that I need to find (or develop!) the u-boot flash driver files. Developing this is a bit out my league. Does anyone know of u-boot source which works for the above mentioned mxic flash chip? Thanks for your time. Regards, Warren Blackwell, AirMagnet, Inc.
