Hi
The customer uses the following code to programming the .srec to Gauge:
from DriveBqBoxClass import BqDrive
from ctypes import *
import sys
from time import sleep
import os
def error(err):
bqsbb_file = "./bqSBB.dll"
bqsbb_dll = CDLL(bqsbb_file)
bqsbb_dll. TranslateErrorbqSBB.restype = c_char_p
error = bqsbb_dll. TranslateErrorbqSBB(c_int(err))
sen = ''
for i in error:
sen = sen+chr(i)
print(sen)
Arry256 = c_char*256
SECTION1_BASE = 0x4000
SECTION2_BASE = 0x100000
SECTION3_BASE = 0x140000

bqsbb_dll = CDLL(bqsbb_file)

prosrec = bqsbb_dll. ProgSegmentsfromSrec(pointer(dataPipeName),c_char_p(srec2_file.encode()))

# prosrec = bqsbb_dll. ProgSegmentsfromSrec(pointer(dataPipeName),c_char_p(srec2_file.encode()),c_int(1))
error(prosrec)
When the ROM platform is 9002 (BQ40Z50), it can be programed normally, but when the ROM platform is 9004, it cannot be programed normally (the IC is not invalid, and it can be programed normally using BQstudio). The error is as follows:
Instruction flash checksum calculated from srec does not match checksum returned from device after programming.
Please help check it.
Thanks
Star
