Regards, Xiaofan ---------- Forwarded message ---------- From: Reinhard Date: Thu, Sep 30, 2010 at 5:19 AM Subject: [lpc21isp] lpc21isp no longer works with ubuntu lucid 2.6.32-25 kernel and ftdi_sio To: lpc21isp Hallo, a patch in the ftdi_sio driver break lpc21isp. (kernels up to 2.6.32-24 work fine). Removing these four lines: -----> /* raise DTR/RTS */ set_mctrl(port, TIOCM_DTR | TIOCM_RTS); <----- -----> /* lower DTR/RTS */ clear_mctrl(port, TIOCM_DTR | TIOCM_RTS); <----- fix the problem Is there a workaround known?
