From a03ffcb9061fc951e116d0925be59db56ca94566 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Thu, 20 Oct 2011 23:14:10 +0000 Subject: Add support for the GOEPEL PicoTAP programmer http://www.goepel.com/en/jtagboundary-scan/hardware/picotap.html This device is actually a JTAG adapter, but since it uses standard FT2232 A interface pins, it can be easily used as SPI programmer (tested it here successfully). PicoTAP supports only 5V output, so one needs to reduce this to 3.3V in a same manner as DLP Design DLP-USB1232H, see http://flashrom.org/FT2232SPI_Programmer#DLP_Design_DLP-USB1232H for details. The PicoTAP pin-out is as follows: PicoTAP | SPI ---------+------- TCK | SCLK TMS | CS# TDI | SO TDO | SI /TRST | - GND | GND +5V | VCC, HOLD# & WP# after 3.3V regulator I managed to run PicoTAP in 10MHz, 15MHz and 30MHz modes (by forcing DIVIDE_BY), against SST25VF016B SPI flash, read/write/erase all worked fine (write seems somewhat slow).
