Other Parts Discussed in Thread: SYSCONFIG, UNIFLASH
Hello all,
picking up on the related post:
Now that I know that configuring the DDR to MSRAM works on the EVM and I am able to flash an application in the EVM I now switched to the custom board.
On the custom board I have following configurations: I have a quad-SPI nor-flash chip (MX25U51245G). Like in the last post I adapted the linker to use the MSRAM instead of the DDR, following this guide, so I removed the DDR-Ram from the SysConfig. I also set the MMCSD-device type to NO_DEVICE.
I also patched the `flash-ospi` src under `\source\board\flash\ospi` following this guideline:
```
I configured on my custom board UART mode and tried pushing the GP image(because my custom board uses a chip with GP architecture).
The programm seems to get stuck when trying to load sbl_null:
```
C:\ti\mcu_plus_sdk_am64x_08_06_00_45\tools\boot>python uart_uniflash.py -p COM16 --cfg sbl_prebuilt/am64x-evm/default_sbl_null_tq.cfg
Parsing config file ...
Parsing config file ... SUCCESS. Found 2 command(s) !!!
Executing command 1 of 2 ...
Found flash writer ... sending sbl_prebuilt/am64x-evm/sbl_uart_uniflash_tq.tiimage

Sending sbl_prebuilt/am64x-evm/sbl_null.release.tiimage: 0%| | 0/271879 [00:00<?, ?bytes/s]
```
Does someone have maybe any idea of what is wrong?
I doublechecked the flash sysconfig to see if it is running. We already have an application(which I run through JTAG loading it into the MSRAM thorugh the load_dsmc.js script using CCS), which uses the same flash sysconfig and patch for the `\source\board\flash\ospi\flash_ospi.c` file. There the QSPI Test seems to work. Both configs (for the sbl and for the app that I tested the qspi) are uploaded with this issue. The one called TQMa64XxL_ALV.sysconfig is the config for the application that was tested.
Btw the test script we use is also included.
Thanks for every hint or help!!!
