(exclude_private and key.startswith('_')) or AttributeError: 'Worksheet' object has no attribute 'startswith'

这个错误是由于在一个名为 `Worksheet` 的对象上调用了 `startswith` 方法,但是该对象没有这个属性或方法。`startswith` 方法通常用于字符串对象,而不是工作表对象。请确保你要调用的方法适用于正确的对象类型。如果你能提供更多的上下文信息,我可以尝试提供更具体的解决方案。

'numpy.ndarray' object has no attribute 'to_csv'
The error message suggests that you are trying to call the `to_csv` method on a NumPy array object, which does not have such a method. The `to_csv` method is a pandas method used to write a DataFrame to a CSV file.
To fix the error, you need to convert your NumPy array to a pandas DataFrame first, and then call the `to_csv` method on the DataFrame object. Here is an example code snippet:
```
import pandas as pd
import numpy as np
# create a NumPy array
arr = np.array([[1, 2], [3, 4]])
# convert the NumPy array to a pandas DataFrame
df = pd.DataFrame(arr)
# write the DataFrame to a CSV file
df.to_csv("output.csv", index=False)
```
In this example, we first create a NumPy array `arr`, and then convert it to a pandas DataFrame `df`. Finally, we use the `to_csv` method to write the DataFrame to a CSV file named "output.csv". Note that we set `index=False` to exclude the index column in the output file.
.\debug\flexspi_nor_debug\GE2406T.out: Error: L6200E: Symbol LPUART1_DriverIRQHandler multiply defined (by fsl_lpuart_1.o and fsl_lpuart.o).
这个错误通常是由于同一个符号被多次定义引起的。在你的情况下,符号 LPUART1_DriverIRQHandler 被 fsl_lpuart_1.o 和 fsl_lpuart.o 两个目标文件重复定义了。
为了解决这个问题,你可以在编译命令中加上参数 --whole-archive,将所有的目标文件都链接进去,这样可以确保所有的符号都被正确定义。例如:
```
gcc -Wl,--whole-archive fsl_lpuart_1.o fsl_lpuart.o -Wl,--no-whole-archive -o output.elf
```
另外,你还可以使用 --exclude-symbols 参数来排除重复定义的符号。例如:
```
gcc fsl_lpuart_1.o fsl_lpuart.o -Wl,--exclude-symbols=LPUART1_DriverIRQHandler -o output.elf
```
这样可以排除掉重复定义的符号,从而解决错误。
