IWR1843: 关于L2 RAM大小配置问题

Part Number: IWR1843


各位专家好,

参考mmwave_automotive_toolbox_3_6_0\labs\lab0007_medium_range_radar工程,现想增加DSS 内DSPL2 堆栈大小,工程内原始宏定义为 #define MMW_L2_HEAP_SIZE    0x19000U。

查阅1843 DSP L2内存大小

和工程内.cmd配置一致

现在问题如下:

1、个人理解DSP L2ram应该总共可分配256KB大小内存,但是修改宏 MMW_L2_HEAP_SIZE    超过0x20000U 就会编译报错,报错如下

"../dss_mrr_linker.cmd", line 47: error #10099-D: program will not fit into available memory. run placement with alignment fails for section ".l2data" size 0x25007 . Available memory ranges:
L2SRAM_UMAP0 size: 0x20000 unused: 0x18fbf max hole: 0x18fa4
L2SRAM_UMAP1 size: 0x20000 unused: 0x44e0 max hole: 0x44e0

齐静雯问题出在哪里?

2、有无相关cmd配置内存的说明文档?

谢谢解答
