Table 5-1 shows the boot modes supported by ROM code.
| Boot Mode | Boot Media | ZCZ-C & ZCZ-S Package | ZCZ-F (SIP) Package | ROM activity |
|---|---|---|---|---|
| QSPI(4S),50MHz | QSPI Flash | Supported | Not Supported | ROM configures OSPI controller in QSPI 4S mode and downloads image from external flash, supports UART fallback boot mode if any failures |
| UART | External Host | Supported | Supported | ROM configures UART0 with baud rate of 115200 bps and downloads image from external PC terminal using x-modem protocol |
| QSPI(1S),50MHz | OSPI Flash | Supported | Not Supported | ROM configures OSPI controller in QSPI 1S mode and downloads image from external flash , , supports UART fallback boot mode if any failures |
| OSPI(8S),50 MHz, 0x8B | OSPI Flash | Supported | Supported | ROM configures OSPI controller in 8S mode and downloads image from external flash, , supports UART fallback boot mode if any failures |
| DevBoot | N/A | Supported | Supported | To support SBL development,R5-will come up with ROM eclipsed, PLLs are not initialized, No L2, TCMA and TCMB PBIST are performed, No L2 memInit |
| xSPI (1S->8D) , 25 MHz, SFDP | OSPI Flash | Supported | Supported | ROM configures OSPI controller in xSPI 8D mode ,Reads SFDP table for read command and downloads image from external flash, Flashes with SFDP are of JEDEC standard Rev D only supported |
