Part Number: TDA4VMXEVM
Hi TI members:
Form thread, there are two propuse for Boot EEprom
1. I2C Boot EEPROM was included in the system for customers who might want to utilize/test the I2C boot interface
2. general I2C memory storage
And my question as below
Q1: For firest propuse, if I want to put the some RTOS file who boot by SBL way. It seem Boot EEprom size is not enough.
AT24CM01 only have 1Mbits(128KB), but right now the small size of RTOS's tiboot3.bin build by myself is 124KB, and still not to count sysfw.bin & app size.
So this propuse seem can't achieve on EVM board, right?
Q2: Is it possible to save BOOT Switch Config (include SW8 / SW9 settings) into Boot EEprom,
and let TDA4 Boot ROM directly read configs from Boot EEprom, not form pins?
If you need more information about questions,
please let me know,
Thanks a lot!!!

Hi Sentinen Chen,
1) Please refer: http://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos_auto/docs/user_guide/developer_notes_sbl_boot.html
SBL Supports OSPI & SD boot mode so I2C boot is not supported on SDK. I even checked Linux SDK th only supported modes are OSPI/SD/eMMC & UART.
2) I checked with ROM expert and the answer is No. It is not supported for TDA4VM.

Hi Keerthy:
Thanks for your reply.
For my two questions are all not supported.
I hope to make sure the "not supported" mean
1. "feature not support right now, but will supported in the future.",
or 2. "there is no plan to supported the two feature"

Hi Sentinen Chen,
For question:
1) This is not coming in the next release for sure. There is no plan to eventually support this as of now.
2) This will be not supported by ROM. This is confirmed.
Hope this answers your questions.
Thanks,
Keerthy
