Hi I am trying to use J-Flash with an AT91SAM7S256 via USB/JLink.
Trying to use the command "Read Back", from a connected device causes the error listed below.
This error is apparent with version V379z02, V378d, but version V374m works OK.
Edit: v374m works if initial JTAG speed is 10KHz, the other versions do not. this was the main project difference between the versions that I noticed.
- 1024 sectors, 1 range, 0x100000 - 0x13FFFF
- ERROR: Write memory error @ address 0x00200000, word access: Memory access timeout.
Failed to verify RAMCode for CPU clock frequency detection!
- ERROR: RAM check failed @ address 0x00200000.
- ERROR: Write: 0xE7FEE7FD E07CE062
- ERROR: Read: 0xAAAAAAAA AAAAAAAA
- ERROR: (0 bytes of RAM have been checked successfully)
- ERROR: Failed to read back target memory
Disconnecting ...
- Disconnected
