Boot mode is selected via two Mode pins at B2B connector J2. By default the TE0724 supports JTAG and SPI Boot Mode. Connecting a SD Card via B2B connector to MIO Pins (See SD Card Interface) gives the possibility to boot from SD Card. The Mode pins are pulled up at the module.
Boot mode | MODE1 J1-2 | MODE0 J1-4 |
|---|---|---|
| JTAG (cascade) | LOW | LOW |
| invalid | LOW | HIGH |
| SPI | HIGH | LOW |
| SD CARD (not on module) | HIGH | HIGH |
