5335 - All FPGA: Does Non-JTAG TransFR support I/O release during TranFR?
Definition:TransFR (Transparent Field Reconfiguration) is a technology that helps minimize system interruption. This is supported through JTAG and Non-JTAG port (example Wishbone). However, there are some disadvantages of Non-JTAG TransFR. It does not allow user to release I/Os at a specific time during TransFR. It does not allow user to customized I/O value during TransFR. I/O values are kept as is.
For further information, you may refer to Minimizing System Interruption During Configuration Using TransFR. The document can be downloaded at the Lattice website.

Why FPGA Programming Failure When JTAG Chain Has 7 or More Devices?
DESCRIPTION When programming Lattice FPGA devices via SPI Flash using a JTAG chain, the Erase-Program-Verify (EPV) operation fails deterministically starting from the 7th device in the chain. Chains of 6 devices or fewer complete SPI Flash EPV ...

No, it is not possible to set PERSISTENCE = ON in order to preserve the JTAG to SPI port in the configuration logic while simultaneously using the SSPIA component to access internal configuration logic from the FPGA fabric (PERSISTENCE = OFF). If ...

No. While the SED is running if the user tries to access the device using any non-jtag port (like WB, I2C, SPI or CPU) the SED will be terminated.
