The default DA (MTK_AllInOne_DA.bin) does not work for all devices.
Let’s fix the Status Ext RAM Exception error. Try these methods in order, from simplest to most technical.

Include logic analyzer screenshots showing failed vs successful DRAM initialization sequence.
Some scatter files contain incorrect memory layout addresses. If the ram_headers or memory regions are misconfigured for your specific device, the flashing process triggers an exception when trying to access non-existent or protected memory zones. The default DA ( MTK_AllInOne_DA
High-speed data transfer to RAM requires a stable physical connection.
The "Status Ext RAM Exception" is a common communication error encountered when using SP Flash Tool to flash firmware onto MediaTek (MTK) Android devices. Let’s fix the Status Ext RAM Exception error
What it means: The error essentially translates to an "External RAM Exception." When SP Flash Tool attempts to write data to the device, it relies on the device's RAM (Random Access Memory) to temporarily store data during the process. This error indicates that the tool cannot properly communicate with or write to the device's external RAM. The connection was likely established initially, but dropped or failed during the data transfer handshake.
