Boot ROM Differences2 Boot ROM DifferencesThis section provides information on the differences between Boot ROM version 2.x and 3.x. TheBoot ROM is implemented in all of the PXA3xx family processors and the Tavor processor. Table 1describes which processor is implemented with the different versions of the Boot ROM.Table 1:Version 2.xx and Version 3.xx High Level DifferencesProcessorSteppingBoot ROMVersionPXA32x B1/B2;Tavor A0Version2.22PXA32x C0Version3.38PXA301 A1andPXA300 A1Version3.19Non-TrustedPXA31x A1;Tavor B0.aVersion3.27JTAGRe-enablement(only for trustedplatforms) 1 No No No No YesDownload viaUSB1.1(differential/SE)Download viaUSB2.0Download viaUSB OTGDownload viaUARTTIM/NTIMSupportNo No No Not applicable forPXA31x A1;Yes (default) forTavor B0.aNo No No Yes (default) forPXA31x;Yes with (TIM)/(NTIM) overridebut only for TavorB0No No No No NoNo No No Yes YesPXA31x A2;PXA302;PXA312 PoPTavor B0.bAll Version 3.32except PXA31x A2Version 3.33Trusted andNon-TrustedYes (default) except forPXA31x A2Not applicable forPXA302;Yes with TIM/NTIMoverride but only forTavor B0;Yes (default) forPXA310 A2No No NTIM NTIM TIM/NTIM1.
