SPRACR5A february 2020 – may 2023 AWR2243
TI’s AWR2243 device supports interfacing with an SDF to obtain the images to be loaded as a part of the bootloading process. During the pre-production phase, the ROM is eclipsed and the majority of the execution of the MasterSS and RadarSS firmware happens from the RAM. Hence, the image sizes being considerably large, are loaded faster when present in the SDF with a QSPI interface.
The flash programmer connects to the device over UART. Specifics are as follows:
Commands ‘Write File to SFLASH’ and ‘Write File to SRAM’ support a maximum data chunk size of 240 bytes only.
The file is split into N commands where:
N = (file size/240) + ((file size%240) ? 1 : 0)
