Looking at Table 3.2 in the Lattice ECP5 Usage Guide. This is testing that a OTP and few internal use only flags are cleared. Why? Was there some other intention?

I am having trouble programming the FPGA on a v3.0.8 board

I have copied the blink_85f.bit file onto the ESP32.

When I run:

import ecp5
ecp5.prog("blink_85f.bit")

then the blue LED lights, but nothing else happens and the board hangs. The FPGA doesn't appear to be programmed properly and the ESP32 becomes unresponsive with serial or FTP.

Any ideas what I am doing wrong?

I have already run import ecp5setup and configured WiFi etc.

hello,

your project is interesting because i posted a similar project but with
a machx02
https://github.com/monk31/wifi_lattice

I use the SPI bus from Lattice that i configure in slave
and it works well

but for the jtag part, i didn't use the spi characteristic in esp32 and
i see that your program work
so i'm curious to your experience with jtag because i didn't make
complete test
