I read sometimes that there is a new driver but I didn't understand how to use. Now, I understand from you, that I need to use the option --enable-ftdi and the config files under ftdi subdirectories. Thanks, I will probe it :D (again, I read sometimes that there is a new driver but nowhere explain how to use, thanks again).
Moreover, I have more extra information: I am using adapter_khz 50 Insted of the original (from pandaboard files) jtag_rclk 6000 (because I had some anothers problems). When I wrote the first mail of this thread, I was using in the cfg file: ... load_image u-boot-linaro-stable/spl/u-boot-spl.bin 0x40304350 bin load_image u-boot-linaro-stable/u-boot.bin 0x80100000 bin load_image kernel/uImage 0x80200000 load_image kernel/uInitrd 0x81600000 bin ... It fails when it was transfer uImage with the message: Error: 30973 77247 ft2232.c:592 ft2232_read(): couldn't read enough bytes from FT2232 device (0< 12) Error: 30974 77247 ft2232.c:844 ft2232_send_and_recv(): couldn't read from FT2232 But after that, when I tried using telnet I leave in the file: ... load_image u-boot-linaro-stable/spl/u-boot-spl.bin 0x40304350 bin load_image u-boot-linaro-stable/u-boot.bin 0x80100000 bin ... And I made with telnet: load_image kernel/uImage 0x80200000 In this manner, a lot of times it work and some of them fails with the error: Invalid ACK 0x6 in JTAG-DP transaction So, I put a delay in the cfg file and now it works better: ... load_image u-boot-linaro-stable/spl/u-boot-spl.bin 0x40304350 bin load_image u-boot-linaro-stable/u-boot.bin 0x80100000 bin sleep 2000 load_image kernel/uImage 0x80200000 load_image kernel/uInitrd 0x81600000 bin ... Is only extra information. I will try, as I said, to use the new driver. Thanks Andreas (and Mathias that asked me about the jtag clock).
