Have you tried using the SVF or XSVF support to do that?

That's the only way to do it for now; we d

hi ALL:
I am reading src\jtag\drivers\jlink.c
From JLink USB protocol manual there is 3 x 2048 Bytes buffer to store
tdi/tms/tdo data.
Any one knows why it have changed to 256Bytes from the code?
//#define JLINK_TAP_BUFFER_SIZE 2048
#define JLINK_TAP_BUFFER_SIZE 256
//#define JLINK_TAP_BUFFER_S
hi ALL:
From code :
+/* We use the maximal value observed */
+#define JLINK_TAP_BUFFER_SIZE 390
+
+static int tap_length;
+static u8 tms_buffer[JLINK_TAP_BUFFER_SIZE];
+static u8 tdi_buffer[JLINK_TAP_BUFFER_SIZE];
+static u8 tdo_buffer[JLINK_TAP_BUFFER_SIZE];
+
Does it means SAMPLE op will
