Hello, I trying to debug a firmmware made for my company by an external supplier. The fw was tested in the past with Mon166, but the supplier doesn't release the Monitor configuration, so I trying to reconfigure it in bootstrap mode with monitor in RAM, but the Monitor cannot start giving an error like "Cannot write at address E71A00".
My configuration is:
TARGET FIRMWARE CONFIGURATION In Start167.A66 the external RAM is on Chip Select 0, address 0x0 range 128K. In Options for Target the external memory is: ROM: 0x0, 0x10000 RAM: 0x10000, 0x10000
MONITOR CONFIGURATION After the copy of the configuration of User167 I set in CONFIG.INC the CODE_START to 0H, the DATA_START to 01F800H, the VECTAB to 08000H. The chip select are configured in same mode like the Start167.A66 of target firmware. In Options for Target the external memory is: RAM: 0x0, ox20000
I'm not able to solve myself this problem. Please, help me. Thank you, Marco
