It's a AT91SAM9263 at 180 Mhz.

jtag_rclk sets the clock to 2 khz (which I tested originally), so I
tried 2000 khz instead. Not better.

Not better, unfortunately. Still the exact same behaviour. Here is my
interface file:
interface ft2232
ft2232_layout jtagkey
ft2232_device_desc "USB-A9263"
ft2232_vid_pid 0x0403 0x6010
adapter_nsrst_delay 200
jtag_ntrst_delay 200
reset_config srst_pulls_trst
script target/at91sam9263.cfg
jtag_rclk 2000
and the OpenOCD output:
$ ../src/openocd -f ./interface/calao-usb-a9263.cfg
