I appreciate the information, and I will check the upcoming SDK release for PSRAM PHY tuning support. I would also like to ask whether you have any information about the abnormal behavior we are seeing with single-byte PSRAM accesses. The APS12808L requires a minimum two-byte write transaction and uses the DQS/DM signal to mask the byte that should not be updated. When the R5F performs an 8-bit write to the OSPI1 memory-mapped region, is the AHB byte enable automatically converted into the appropriate DQS/DM output by the OSPI1 Direct Access Controller? I would particularly like to confirm whether memory-mapped uint8_t reads and writes are supported for this PSRAM configuration, and whether any additional SysConfig or register setting is required. If this is unrelated to PHY tuning and should be investigated separately, I am happy to create another E2E ticket.

The PSRAM is accessed through the OSPI1 memory-mapped region starting at: 0xA0000000 I would like to enable OSPI PHY mode, DQS-based read capture, and Direct Access Controller mode. Could you please provide the recommended SysConfig settings and OSPI register settings for this configuration? The registers and fields I am currently reviewing are: OSPI_FLASH_CFG_CONFIG_REG PHY_MODE_ENABLE_FLD PIPELINE_PHY_FLD ENABLE_DTR_PROTOCOL_FLD ENB_DIR_ACC_CTLR_FLD OSPI_FLASH_CFG_DEV_INSTR_RD_CONFIG_REG DDR_EN_FLD OSPI_FLASH_CFG_RD_DATA_CAPTURE_REG DQS_ENABLE_FLD DDR_READ_DELAY_FLD My questions are: Which SysConfig option enables OSPI1 PHY mode for PSRAM? Which of the above register fields must be enabled? Is PHY calibration or DLL tuning required for Octal DDR PSRAM? Can the existing OSPI NOR Flash PHY tuning procedure be used for PSRAM? Is there an MCU+ SDK PSRAM example that uses PHY mode? I also need to perform 8-bit memory-mapped writes: volatile uint8_t *psram = (volatile uint8_t *)0xA0000000U; psram[0] = 0xAAU; The APS12808L requires a minimum two-byte write transfer and uses DQS/DM to mask the byte that must not be updated. Does the AM261x OSPI1 Direct Access Controller automatically convert an R5F 8-bit store into a two-byte PSRAM write with the appropriate DM value? If not, what is the recommended method for updating a single byte in the PSRAM? A known-good SysConfig file or an OSPI1 register dump would be very helpful.
