I observed strange cmsisDAP behavior when building openFPGALoader with
Clang/musl in release mode: CmsisDAP:display_info() shows the correct
hardware capability that supports JTAG,
...
firmware version : 0254
hardware capabilities : 13
SWO trace buffer size : NA
...
but the detection of JTAG fails in the constructor with a strange
response sequence,
Hardware cap 00 01 00
JTAG init failed with: JTAG is not supported by the probe
With some digging, it's found that the CmsisDAP::xfer() method without
an instruction parameter may be called by the constructor with a rx_buff
pointer overlapping with _ll_buffer, for which memmove() instead of
memcpy() should be used. The behavior of memcpy() is undefined when dst
and src overlap.

Add board definition and FPGA part ID for the MILIANKE S200 EG4D20
development board. Also update related documentation and outdated URL.
Tested ok by loading bitstream to SRAM and FLASH.

ANLOGICCABLE_VIDv1 should keep the old ANLOGICCABLE_VID to compatible
with the original device.

Programming to SRAM works. Programming flash works with a renamed
spiOverJtag bitfile - cs(g)484 is different from fg(g)484, but the
configuration flash IOs all end up on the same pads in the end.
- esp_usb_jtag: added xfer method to handle/simplify libusb_bulk_transfer calls
- src/esp_usb_jtag.cpp: simplify some operations
- src/esp_usb_jtag.cpp: writeTDI: fixed rx buffer index, added a basic code to handle end transaction
- src/esp_usb_jtag.cpp: writeTMS: store and uses _tdi & _tms
- src/esp_usb_jtag.cpp: toggleClock: re-uses _tdi/_tms
- src/esp_usb_jtag.cpp: writeTDI: ditto
- esp_usb_jtag: fixed verbosity level/be more quiet
- esp_usb_jtag: fixed writeTDI with end and tms transition: now integrated instead of distinct sequence. Fixed TDI value with tms transition. Working with ECP5
- esp_usb_jtag: added optional parameter to lower timeout error (useful when it's time to flush the device)
- esp_usb_jtag: fixed writeTDI when tx is NULL
- copy dirtyjtag to esp_usb_jtag, it compiles
- copy protocol definiton, defines and private data/struct from openocd esp_usb_jtag.c
- ulx3s_esp board with esp32s3 cable
- esp_usb_jtag specify usb vid:pid in jtag.cpp
- hardcode usb interface and endpoints
- getting caps
- set chip id (not applicable for fpga)
- tms write done, untested
- cleanup and toggle clk
- 32bit counting
- setting divisor (todo read base freq)
- div range within 1-255
- base speed from descriptor
- fix doc typo with swapped tms/tdi some cleanup but it doesn't work.
