Hello,

I have problem for SAM-BA CDC.
MCU is 7S64 and PC is windows XP sp3.
Used SAM-BA CDC is "sam-ba_cdc_2.9.xp_vista.exe"

1. After boot loader had been copied to flash, 7s64 board
attached to computer and it can be detected to COM9 virtual
serial port.
But SAM-BAxxxx.exe can not detect board.

2. Legacy driver which is called atm6124.sys is operated well with
SAM-BA 2.0 on same computer.

3. Another board has 7SE512 , it is good with SAM-BA CDC on same
computer machine.

4. 7s64 chip was bought at 2004. Does it have problem for SAM-BA CDC?
The chip marking is "SAM7S64 AU-001 58814G 0529 5P1356".

5. with DataSheet SAM-BA boot chapter, I have tested manually with RS-232 monitor "RealTerm".
sent 128, 128, 35 and then , 7s64 returned 0x0A, 0x0D, 0x3E.
I think 7s64's identification routine is operating correctly, but SAM-BA boot routine has some problem to work with SAM-BA CDC.


Can anybody help me?
