AM2434: Max Boot up time & Max Injection current into An GPIO pin

Rajesh K

Part Number: AM2434

Tool/software:

Hi Team,

I am not able to find the below details from the datasheet.

1) max boot up time for the SOC from UART and OSPI mode separately ? We need this value to configure the Boot mode pins to configure for the PWM as an alternate function.

2) Max. injection current into a GPIO pin for the device ?

Appreciate your help at the earliest . !

Regards,

Rajesh K

Hi Rajesh,

For Q1:

Maximum booting time are not profiled, you can find some timings on SBL_OPSI as a reference in the MCU + SDK documentation:https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/10_01_00_32/exports/docs/api_guide_am243x/DATASHEET_AM243X_EVM.html#autotoc_md507 but these do not represent the max boot up time.

The maximum boot-up time might not be that relevant for you because you can change the pins to PWM function once the Application boots. What would be more relevant in your case is the set-up time for the boot pins, this is already defined in the AM243 datasheet in Table 6-12.

For Q2: I am reassigning this to the domain expert, please wait for their reply.

Best Regards,

Meet.

Hello Rajesh,

Thank you for the query.

Could you please start a new thread for Q2 to be assigned to the right expert.
