TrueTouch Multi-Touch CY8CTMA140怎么通过I2C进行固件升级

你好，
我正在尝试升级TtrutouCH多点触摸CY8CTMA140的固件，而不使用SoC程序员，而是通过I2C接口。我得到了固件文件“ZXXL7C.HEX”和“CT5138V0.0.HEX”（每个70.8KB大小）来自真正的供应商。
以下是我尝试升级固件时的问题，
阅读固件版本：
1。我遵循下面提到的顺序
W 24 00 00 FF A5 00 00 01 02 03 04 05 06 07
W 24 11
然后，当我阅读时，我得到了0x85 0x00作为固件版本，在编程新固件（“ZXXL7C.HEX”和“CT5138V01，HEX”）之后，我得到了相同的固件版本。
用“CT5138V01、HEX”/“ZXXL7C·HEX”更新固件
1。我遵循下面提到的顺序
W 24 01
读回BLY状态BIT4——不设置，重试10次，延迟30MS
W 24 00 00 FF A5 00 01 02 03 03 04 05 06 07闪光命令发起记录-通过
检查记录
制备记录
闪光记录
注意：在闪存记录I2C中，只有当我们设定100kHz的I2C速度时，才通过，当我们把速度设定为400千赫时，它就失败了。
当我测试多点触摸时闪烁，第二个触摸坐标出现在垃圾值（例如：X - 1900 Y - 1000）中，这个值也不一致。这个“CT5138V01.HEX”/“ZXXL7C.HEX”是我在设备中编程的正确固件吗？
2。在编程新固件之后，重新启动设备，PCT回到旧状态第二触摸坐标始终保持（X-0x00 y -0x00），并且没有垃圾值。是否需要在启动后每次编程新固件，还是一次可编程？

  Hi,
    I'm trying to upgrade the firmware of the TrueTouch Multi-Touch CY8CTMA140 without using the SOC programmer but through I2C interface. I have got the firmware files "ZXXL7C.hex" and "CT5138V01.hex" (each of 70.8Kb size) from Truly vendor.
    Following are the issues when I try to upgrade the Firmware,
         
               
    Reading the Firmware version:
    1.       I’m following the below mentioned sequence
    W 24 00 00 FF A5 00 01 02 03 04 05 06 07
                            W 24 11
                      Then when I read, I got 0x85 0x00 as firmware version, after programming the new firmware  ("ZXXL7C.hex" and "CT5138V01.hex" ) I’m getting same firmware version.
    Updating the firmware with “CT5138V01.hex” / “ZXXL7C.hex”
    1.       I’m following the below mentioned sequence
    W 24 01
                             Read back BL_STATUS bit4 – Not set, Retry for 10times with delay of 30ms
    W 24 00 00 FF A5 00 01 02 03 04 05 06 07 – Flash command initiate record – Passed
    Check_record
    Prepare_record
    Flash_record
                      Note: During Flash record I2C write passed only when we set the I2C speed in 100khz and it fails when we set the speed as 400khz
                    After flashing when I test the multi touch the second Touch coordinate comes in junk values (Eg: x – 1900 y – 1000) also this values is not consistent. Is this “CT5138V01.hex” / “ZXXL7C.hex” the correct firmware that I have programmed in the device?
    2.       After Programmed the new firmware, restart the device, PCT went back to old state Second touch coordinate always remains (x – 0x00 y – 0x00) and no junk values. Is it need to program the new firmware each time after booting or it is one time programmable?
