Functionality#
This is a dual-JTAG adapter module, which enables the programming of the CPLDs without changing the physical setup of the UltraZohm. It does so by featuring two independent JTAG channels (and a UART), where one JTAG (and the UART) connect to the Zynq-SoM and the other JTAG programs the CPLDs.
Known issues#
None (as currently shipped). The first batch of Rev01 boards lacked a 0R resistor towards the CPLDs’ supply rail, but this has been fixed manually for all boards.
Compatibility#
Rev01 is designed to be applied to the CarrierBoard to replace the Trenz TE0790, see tutorial Upgrades.
