Calypso Firmware moko11
=======================

An upgrade of the firmware in the "Calypso" GSM modem of the Neo 1973
(GTA01) and FreeRunner (GTA02) is available at
http://downloads.openmoko.org/firmware/calypso/


Changes
-------

This firmware corrects the following two defects:

- hardware flow control was not enabled on the serial connection
  between the modem and the CPU, causing FIFO overruns and thus
  data loss

  http://docs.openmoko.org/trac/ticket/1376

- the I/O line used to wake the CPU from suspend on GSM activity
  was not properly initalized, causing the CPU to remain suspended
  on some calls or other activity

  http://docs.openmoko.org/trac/ticket/2231

Both bugs were extensively discussed in the thread at [1].


SHR compatibility warning
-------------------------

moko11 triggers a bug in SHR rootfs images built before February 16,
2009. This bug prevents the GSM subsystem from getting started.

SHR users should therefore make sure they are running a recent image
before upgrading to moko11.

Further details can be found in the commit fixing the bug [2].


Qi and kernel compatibility warning
-----------------------------------

Recent changes introduced an incompatibility between Qi and the
kernel when setting up the GSM modem lines. If using Qi, upgrade the
kernel to at least the following version:

- "stable": commit f19f259d3c1afde8eae53983fd19f61831927413
- "andy-tracking": commit 8df75a337131d835d4dd8509696d684e4fa8970e
