Hi

 

I'm loading the u-boot to the spi flash (M25P64) on a BF537 board, which is a custom board based on the BF537 Stamp board. The board has no parallel flash and only has a M25P64 serial flash. I'm using IGLOO JTAG board to program the u-boot to the serial flash, but met some problems.

 

When I'm using the jtag program, it can successfully detect the BF537 chip. Here's the output of the 'print' command. However, the jtag program complain 'spidetectflash Error: Bus driver missing' when I tried to use 'spidetectflash' to test whether the spi flash can be properly found.

 

jtag> print

No. Manufacturer              Part                 Stepping Instruction          Register

---------------------------------------------------------------------------------------------

   0 Analog Devices            BF537                2        BYPASS               BR

 

Active bus:

*0: Blackfin BF537 EZKit/Stamp compatible bus driver via BSR (JTAG part No. 0)

        start: 0x00000000, length: 0x100000000, data width: 16 bit

jtag> spidetectflash 0

spidetectflash Error: Bus driver missing.

 

I tried on BF1 and BF533 Stamp board. On BF1 board, the spi flash can be found when using 'initbus bf532_bf1', but on BF533 stamp board, it failed to found when using 'initbus bf533_stamp'. Instead, if I use 'initbus bf532_bf1', the spi flash can be found without difficulty.

 

I don't know if the problems come from the jtag program. It says 'JTAG Tools 0.5.1-bf1' when the program firstly run. Any suggestions? Thank you.

 

JJ

I found the reason is that currently the jtag program spi bus is not supported by the BF537.

Mike:

 

IGLOO is something we helped with - and we do support it in the urjtag code - it is the same as a wiggler.

 

The ICEBear is a section 5 product.
