PSOC4100 PLUS EEPROM

@The same program ，went off track in CY8C4126AXI-S433, but CY8C4126AXI-S433 working is Ok

The same program ，went off track in CY8C4126AXI-S433, but CY8C4126AXI-S455 working is Ok，Why？

[Roy_Liu]

Are you using "Em_EEPROM" in your program? What do you see of "went off track in CY8C4126AXI-S433"?

S433 belongs to PSoC4100S family while S455 belongs to PSoC4100S plus, though no much difference.

Hi Roy：

     程序目前没办法给到，客户的描述是CY8C4126AXI-S455上Em_EEPROM程序经过测试没有问题，但是移植到CY8C4126AXI-S433上程序就跑飞了，客户在写EEPROM前一个IO输出高电平，写完成后再输出低电平。观察写多少次后程序跑飞，经观察每次测试不一样，10几次~40几次不能

Hi Halden,

可能还是客户代码逻辑或者延时的问题，我们没有工程，这个问题不好分析。

Thanks,

You'd better share a simple project which can reproduce this issue, then we can analysis the root cause. Seems this two parts have the same FLASH/SRAM size, so this issue should not happen.
