Hi,

I successfully flashed the internal memory the MB9DF126 chip, using the MB9DF126 JLinkScript from JLinkARM_V480f.
I am now trying to configure JFlash to flash the external memory, and get "Could not find CFI compliant flash device" error.
I added a new flash bank with base address = 10000000 and 16bits organization, and then I configured the EBI registers as follows:
InitStep0_Action = "Reset"
InitStep0_Comment = "Reset and halt target"
InitStep0_Value0 = 0x00000000
InitStep0_Value1 = 0x00000000
InitStep1_Action = "Write 32bit"
InitStep1_Comment = "Unlock EBI registers"
InitStep1_Value0 = 0xB0180000
InitStep1_Value1 = 0xEB1410CE
InitStep2_Action = "Delay"
InitStep2_Comment = "Wait for EBI register unlock"
InitStep2_Value0 = 0x00000000
InitStep2_Value1 = 0x00000019
InitStep3_Action = "Write 32bit"
InitStep3_Comment = "Configure Flash mode control register"
InitStep3_Value0 = 0xB0180008
InitStep3_Value1 = 0x00000009
InitStep4_Action = "Write 32bit"
InitStep4_Comment = "Configure Flash access configuration register"
InitStep4_Value0 = 0xB0180028
InitStep4_Value1 = 0x005F0706
InitStep5_Action = "Write 32bit"
InitStep5_Comment = "Configure Flash address configuration register"
InitStep5_Value0 = 0xB0180048
InitStep5_Value1 = 0x000F0000
InitStep6_Action = "Write 32bit"
InitStep6_Comment = "Lock EBI registers"
InitStep6_Value0 = 0xB0180000
InitStep6_Value1 = 0x00000009

From what I read on the forum, this error is likely due to a missing init sequence.
Did any of you already walked that path; do you have hints about what is missing in the sequence?

Thanks in advance,
Pierre

Hi,

It seems the easy way to proceed is to use FSW from Spansion (Fujitsu SoC Wizard) with J-Link.
It allows programming both internal and external memories using a command line interface which is very straightforward to set-up.
