Memtool is a useful debug tool which can read/write some i.MX register. It is default supported in Linux while not supported in Android. This article describse how to integrate memtool into i.MX8MM Android 12 platform, which is also similar in other i.MX new android platform.  

i.MX RT1170 crossover MCUs are part of the Edge Verse™ platform and are setting speed records at 1 GHz. This ground-breaking family combines superior computing power and multiple media capabilities with ease-of-use and real-time functionality. For reducing the overall system cost, RT117x didn't have embeded flash, need external Flash as program storage and XIP place, NXP and third party like IAR, KEIL and Segger all provide mature tool to make Nor Flash‘s programing with their own flashloader, can fulfillment most customer’s application requirement, but still some users need to customize the flash programing algorithm due to programing speed optimization and difference of the nor Flash from different vendor and, such as SFDP support, QE bit's position, default sector size, DDR/OPI/QPI feature, default 3 Bytes/4 Bytes mode and also operating sequence, but the default Flashloader is based on the ROM API, it's hard to debug and customize as there is no source code. This reference demo will use source code Flash operation API instead of ROM API. In addition, it also add two new useful feature, first one is current Flashloader framework can't support some nor flash which need pre-configuration, such as Cypress's S25HL01GT, its sector size is not unified, need to config additionally. This reference demo give some function interface to implement it with 3 bytes/4bytes command mode and DDR/SDR mode, it also improve the original framework by adding read-erase-write demonstration code, which can help user to verify their customized Flashloader without need to copy to IDE every time, improve the efficiency greatly. Second advantage is it can support download flow‘s log generation, by default there is no log info in overall download flow, hard to locate which step(get configure/init/erase/program/verify) the failure occur, this demo code add log function to record every detailed download step, by which users can optimize their download speed, it's helpful for mass production. Developers can also debug and customize depend on their own specific requirement and different nor Flash.

EEPROM selection guide for serial RCON boot. On S32G reference manual, we only ask customer to make sure I2C address of EEPROM is 0xA0, no others requirement. Actually, S32G only supports EEPROM with one 8-bit address byte. For high capacity EEPROM such as AT24C64D@8K bytes, which need two 8-bit word address bytes. Can’t be supported by S32G ROM.   AT24C64D.pdf         AT24C01 has been validated on S32G EVK board, which need one word address byte AT24C01.pdf   Thanks, Lambert
