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
