 ECPDAP allows you to program ECP5 FPGAs and attached SPI flash using CMSIS-DAP
 probes in JTAG mode.
 
+## JTAG Scan Chains
+
+ECP5 FPGAs can be programmed on arbitrary JTAG scan chains; you may need to
+specify `--ir-lengths` and possibly specify a higher `--scan-chain-length`
+depending on the other devices on your scan chain.
+
+However, the attached SPI flashes require that the ECP5 is the only device
+on the scan chain (in other words, the probe TDI and TDO connect directly
+to the ECP5 pins).
