am243x-EVM boot DDR initialization

Other Parts Discussed in Thread: UNIFLASH

Hi,

I'm using am243x-EVM.

I'm loading two files for boot:

1. sbl_prebuilt/am243x-evm/sbl_uart_uniflash.release.hs_fs.tiimage

2. sbl_prebuilt/am243x-evm/sbl_null.release.hs_fs.tiimage

I'm trying to figure out which one of them is initializing the DDR , or maybe both do?

Thanks,

Eli

    Hi Eli,

    In AM243x MCU+ SDK 09.0100.41, both sbl_prebuilt/am243x-evm/sbl_uart_uniflash.release.hs_fs.tiimage and sbl_prebuilt/am243x-evm/sbl_null.release.hs_fs.tiimage should initialize the DDR. One way to check whether a CCS project include DDR initialization or not is to check the example.syscfg file. If the TI DRIVERS --> DDR is checked then the DDR initialization is included, otherwise it is not included.

    Best regards,
