Eu uso o linux-socfpga do repositório github da Altera (o branch master que foi atualizado recentemente) com o meu FPGA DE2-115. A saída da configuração do jtag é:
$ jtagconfig1) USB-Blaster [2-2]
020F70DD EP3C120/EP4CE115
Gostaria de saber se é possível encontrar uma memória USB que eu anexei? Quando eu executo o lsusb nada aparece. Talvez seja o design do FPGA que está errado?
