Good, that means there is communication between the TT-3200 and the CI
board. The firmware version reported by your CI was preventing any
attempt to communicate. A few lines further down from your change is
another version check that decides if polling or interrupts should be
used:
// version 0xa2 of the CI firmware doesn't generate interrupts
if (ci_version == 0xa2) {
ca_flags = 0;
budget_ci->ci_irq = 0;
} else {
ca_flags = DVB_CA_EN50221_FLAG_IRQ_CAMCHANGE |
DVB_CA_EN50221_FLAG_IRQ_FR |
DVB_CA_EN50221_FLAG_IRQ_DA;
budget_ci->ci_irq = 1;
}
The default is interrupts which you say doesn't work. You can try
adding your CI version to the if section test (or rearranging the
whole if/else section so that the two values are always set as per the
if section) to see if polling gets your CAM initialised.
