[FAQ] PROCESSOR-SDK-AM57X: UNIFLASH sequence for different QSPI part number?

Hi,

Please follow below steps:

• Update the pdk_am57xx\packages\ti\board\src\flash folder according to your QSPI specification.
• Once updated, build the board lib.
• Then, you can test read/write to your QSPI by building QSPI diagnostic test(pdk_am57xx\packages\ti\board\diag\qspi), QSPI driver example or both. You can verify the vendor id and manufacturer id of your qspi part number. This will tell you that whether your QSPI is up or not.
• Then, you can build the pdk_am57xx\packages\ti\board\utils\ to get the updated flash programmer according to your QSPI part number in pdk_am57xx\packages\ti\board\utils\uniflash\target\bin\idkAM57Xx\.
• Now, you can follow this link for writing and erasing sequence for UNIFLASH.
  • Only thing you have to keep in mind is that, you have to use uart_idkAM57Xx_flash_programmer.out from pdk_am57xx\packages\ti\board\utils\uniflash\target\bin\idkAM57Xx\ instead of <path\to\uniflash\root_folder>\processors\FlashWriter\idkAM57Xx\uart_idkAM57Xx_flash_programmer.out (as this is default binary compatible with TIEVMs).
• Rest steps will remain same, just build the binaries (MLO,etc.) freshly.

Note - just keep in mind whenever you are using any binary that is prebuilt that may not work with your customBoard as those are compatible with TIEVMs. Therefore, always build the binaries freshly.
