ZQ calibration table
ZQ calibration is SoC temperature dependent. The table below provides some calibration results as a reference:
| Device | ZPROG (two-digit 'zq' parameter) | Calibrated ZDATA on cold start (SoC temperature is low) | Calibrated ZDATA on hot reboot (SoC temperature is high) |
|---|---|---|---|
| ssvb's Cubietruck | 0x2c | 0x10d1800 | 0x10d3900 |
| ssvb's Primo73 | 0x2b | 0x10de800 | 0x10d6900 |
| ssvb's Cubieboard | 0x2b | 0x10dcb00 | 0x10de800 |
| ssvb's Cubieboard | 0x3b | 0x199cb00 | 0x199e800 |
