写一段Python代码： 使用正则表达式，筛选出指定txt文档中“VREF_BF_TRIM= 584.0MV”中间的数字，并另存为一个叫“OK”的txt文件中

import re

# 打开原始文本文件
with open("original.txt", "r") as f:
    content = f.read()

# 使用正则表达式匹配数字
match = re.search(r"VREF_BF_TRIM=\s*(\d+(\.\d+)?)MV", content)

if match:
    # 提取匹配到的数字
    num = match.group(1)

    # 将数字保存到新的文本文件中
    with open("OK.txt", "w") as f:
        f.write(num)
else:
    print("No match found.")

其中，`original.txt`为指定的文本文件名，`VREF_BF_TRIM= 584.0MV`为待匹配的字符串，数字`584.0`将被提取并保存到新的文本文件`OK.txt`中。如果没有匹配到，则输出提示信息。

写一段Python代码： 使用正则表达式，筛选出指定txt文档中“VREF_BF_TRIM= 584.0MV”中间的数字，然后将筛选出来的所有数字分别存进一个叫“OK”的xlsx的单元格中

import re
import openpyxl

# 打开txt文档
with open('example.txt', 'r') as f:
content = f.read()

# 使用正则表达式筛选出数字
pattern = r'VREF_BF_TRIM=\s+(\d+\.\d+)MV'
match_list = re.findall(pattern, content)

# 将数字存进xlsx单元格中
wb = openpyxl.Workbook()
ws = wb.active

for i in range(len(match_list)):
ws.cell(row=i+1, column=1, value=float(match_list[i]))

wb.save('OK.xlsx')

根据您提供的信息，似乎是内存训练过程中出现了错误。错误信息中指出了CH1内存信息不同的问题，以及训练过程中的一些参数和配置。其中，"Mcu Channel 1 AES configuration begin... AES bypass end... TZC configuration begin... TZC bypass end... use_0x14 == 0xb0100 ctl_cfg_begin"等信息表示内存控制器的一些配置和初始化过程。而"rank 0 wdqlvl! r2r_diffcs_dly = 4 r2w_diffcs_dly = 7 w2r_diffcs_dly = 4 w2w_diffcs_dly = 6 r2w_samecs_dly = 5 rank 0 ch 1 training fail"则表示在对CH1的rank0进行写数据时出现了训练失败的情况。

具体的原因可能需要进一步分析，可能与内存硬件、时序参数、内存控制器等方面有关。建议您尝试重新启动或重新插拔内存模块，并检查是否有硬件故障或不良连接的情况。同时，您也可以检查内存访问时序参数和内存控制器的配置是否正确。如果问题仍然存在，建议您查看更详细的错误信息或寻求专业的技术支持。
