器件型号：TDA4VM

您好、TI 专家

我想为 C71和 A72分配 MSMC 存储器作为第3种解决方案、但遇到了错误

感谢您的任何建议

我作为学员所做的详细步骤、

SDK 版本：08.00.12

SYS：Linux + RTOS

1. 修改 tidl 配置文件，并重建 CNN 模型，重新生成 model.bin

'tidl_j7_08_00_00_10\ti_dl\testvecs\config\cimport\device_config.cfg

MSMCISPIZE _KB = 3872

2. linux：‘vision_apps\apps\basic_demos\app_rtos\rtos_linux\gen_linker_mem_map.py’

dmsc_msmc_size   = 64*KB;
mpu1_msmc_addr   = msmc_mem_addr;
mpu1_msmc_size   = 128*KB;
c7x_1_msmc_addr  = mpu1_msmc_addr + mpu1_msmc_size;
misc_msmc_stack_size = 32*KB;
c7x_1_msmc_size  = 4*MB - mpu1_msmc_size - dmsc_msmc_size - misc_msmc_stack_size;
dmsc_msmc_addr   = c7x_1_msmc_addr + c7x_1_msmc_size + misc_msmc_stack_size;

获取"linker_mem_map.cmd"文件，并替换相应的文件
