Hi all,

 

 

 

We've manufactured a custom board which has BF561 as the base processor and MD8832 as the flash memory. Since, we've an  ICEBEAR JTAG adapter so we thought that it would be compatible for programming the Flash memory. After manufacturing the board we found that the ICEBEAR adapter is compliant for CFI based flash devices whereas our flash memory does not fall under this category and is a non CFI compliant.

 

Can anybody suggest a solution to program the NAND flash (MD8832) (ie. Program, Erase & compare ) using any of the  existing methods in uclinux rather then using ICEBEAR adapter or any other JTAG adapters.

 

Any help in this regard will be highly appreciated.

 

 

 

with regards

 

Kannan

no NAND device is CFI conformant as CFI is for parallel NOR flashes (which NAND obviously is not)

 

i dont think any JTAG device supports programming of NAND flashes currently

 

just use U-Boot to program the flash

Hi Mike,

 

 

 

Thanks  for the reply.

 

How can we accomplish this because we are stuck at this point with our board. Using the JTAG adapter (ICEBEAR) we would achieve the programming of flash memory in our BF561 Ez-Kit lite, but how can we achieve the same in our custom board without the JTAG adapter and using u-boot to program the MD8832 Nand flash.

 

"just use U-Boot to program the flash"

 

Can you explain us in detail or give some related links.

 

 

 

with regards

you must have some other flash on your board other than NAND ... program u-boot into that

 

you can find u-boot documentation here: http://docs.blackfin.uclinux.org/doku.php?id=bootloaders:u-boot
