| In a few of the designs we have done, like the [[./pluto|PlutoSDR]] and [[./m2k|M2k]] there hasn't been enough room on the PCB for serial and JTAG, so we put it on a small breakout board, which communicates to the main platform with a small 10 pin ribbon cable. | In a few of the designs we have done, like the [[./pluto|PlutoSDR]] and [[./m2k|M2k]] there hasn't been enough room on the PCB for serial and JTAG, so we put it on a small breakout board, which communicates to the main platform with a small 10-pin ribbon cable, which is known as the [[adi>ADALM-UARTJTAG]]. |

| | ====== Hardware ====== |
| | Analog Devices provides a small adapter board [[adi>ADALM-UARTJTAG]] to be used for JTAG and UART, in order to make that easier for programming and debugging. You are encouraged to use this on your designs for the same reason we do - the standard JTAG connector is huge, and there are times where good old fashion console UART is valuable for doing debug. The 1.8V supply on the connector above is the I/O voltage, and can be used anywhere between 1.8V and 3.3V. |
| | |
| | In the box, you should have received the UARTJTAG board, ribbon cable, and jumper. |

| | |
| | The PCB includes a jumper, which forces the Zynq to HALT on JTAG. This is great for halting, and not allowing anything to run, but does pull down a chip select for SPI flash, and will not allow the SPI flash to be found by the on-chip bootloader, or by U-Boot. (If you are loading a U-Boot over JTAG). |
| | |
| | The pin connector is likely inserted into the ribbon cable: |

| | |
| | but can be removed, and either soldered to the PCB, or left in the ribbon cable, so you don't lose it. |
