I have a SW256N 32MB NOR flash connected to CS0 of my i.MX27 SoC. In my board cfg file I have included the following lines describing 3 banks of my NOR which has 16 banks:
# The Visstrim SM10 board has a NOR flash on CS0 flash bank cfi 0xc0000000 0x00200000 2 2 imx27.cpu flash bank cfi 0xc2000000 0x00200000 2 2 imx27.cpu flash bank cfi 0xc4000000 0x00200000 2 2 imx27.cpu However, if I try doing "flash probe 0" this is what I get. It can read properly manufacturer ID and device ID but it is unable to read QRY string properly: Debug: 255 156350 command.c:68 script_debug(): command - probe Debug: 256 156360 command.c:77 script_debug(): probe - argv[0]=ocd_flash_probe Debug: 257 156370 command.c:77 script_debug(): probe - argv[1]=0 Debug: 258 156380 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 259 156390 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 260 156400 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 261 156410 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 262 156420 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 263 156440 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 264 156450 arm7_9_common.c:2264 arm7_9_read_memory(): address: 0xc0000000, size: 0x00000002, count: 0x00000001 Debug: 265 156460 target.c:1359 target_read_u16(): address: 0xc0000000, value: 0x0001 Debug: 266 156470 arm7_9_common.c:2264 arm7_9_read_memory(): address: 0xc0000002, size: 0x00000002, count: 0x00000001 Debug: 267 156490 target.c:1359 target_read_u16(): address: 0xc0000002, value: 0x227e Info : 268 156500 cfi.c:2181 cfi_probe(): Flash Manufacturer/Device: 0x0001 0x227e Debug: 269 156510 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 270 156520 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 271 156530 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 272 156540 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 273 156550 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 274 156560 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 275 156580 arm7_9_common.c:2264 arm7_9_read_memory(): address: 0xc0000020, size: 0x00000002, count: 0x00000001 Debug: 276 156590 arm7_9_common.c:2264 arm7_9_read_memory(): address: 0xc0000022, size: 0x00000002, count: 0x00000001 Debug: 277 156610 arm7_9_common.c:2264 arm7_9_read_memory(): address: 0xc0000024, size: 0x00000002, count: 0x00000001 Debug: 278 156620 cfi.c:2219 cfi_probe(): CFI qry returned: 0x20 0xf0 0x80 Debug: 279 156630 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 280 156640 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Debug: 281 156650 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000004 Debug: 282 156670 embeddedice.c:451 embeddedice_write_reg(): 0: 0x00000005 Error: 283 156680 cfi.c:2233 cfi_probe(): Could not probe bank: no QRY User : 284 156690 command.c:400 command_print(): probing failed for flash bank '#0' at 0xc0000000 Does anyone know what could I try to solve this problem?
