你好
当我使用ti processor sdk rtos-j721e evm的mmalib库时，我发现mmalib_bufParams2D_T的data_Type使用mmalib_INT32，并使用整数数组作为输入，程序正常。
但当我使用浮点数组作为输入时，无论data_Type是 MMALIB_FLOAT64 还是MMALIB_FLOAT32，代码都会被卡住。我该怎么办？
结果是：
[C7x_1]5292.079344秒：360
[C7x_1]5292.079366秒：statusinit=10000
[C7x_1]5292.079381秒：statusexec = 0
MMALIB_LINALG_MatrixMultiply_ixX_ ixX_oxX_ init_ checkParams（）中存在问题。查找定义并发现当MMALIB_STATUS=10000时，意味着不支持的输入数据类型，但我认为因为它存在，例如MMALIB_FLOAT64，所以使用时应该没有问题。
