[U-Boot] Issues when BDI2000 accesses the emtpy flash

[Spark Zhao]

Hi, All

My platform is FSL8347, Flash : SPANSION S29GL01GP 128MB, base address
0xf8000000, RAM 256MB DDR2.  BDI2000 with 1.22 firmware for MPC82xx/83xx/..

I erased the first sector of the flash, then tried to access the empty flash
by the command "md 0xf8000000", it always report that "# SAP: read access
failed". 

I changed the bdi2000 config file with adding "RCW 0xA0500000 0x08040000",
but when I dump the register it displayed

rcwlr: 0x00000000  0

rcwhr: 0x00000000  0

and the flash still can't be accessed, can anyone please help?

 

Below is what I got from the bdi2000 shell:

- CONFIG: loading configuration file passed

- CONFIG: loading register definition passed

- TARGET: processing user reset request

- BDI asserts HRESET

- Reset JTAG controller passed

- Bypass check: 0x00000001 => 0x00000001

- JTAG exists check passed

- BDI overrides HRCW (0xA0500000 0x08040000)

- BDI removes HRESET

- Target PVR is 0x80830031

- Target SVR is 0x80500030

- BDI sets breakpoint at 0x00000100

- BDI resumes program execution

- Waiting for target stop passed

- TARGET: Target PVR is 0x80830031

- TARGET: resetting target passed

- TARGET: processing target startup ....

- TARGET: processing target startup passed

 

My config file as below:
