- Hi VJ,
The fact that you are making it to u-Boot (after the SPL) means you are pretty much there!
The bad CRC message (before you saved your environment) means that either:

We have recently received 10 MitySOM-5CSX boards, but we have not been able to boot correctly.
Up to now we have been using the evaluation board with included SOM-boards where we have:
- switched from booting from MMC to on-board...

- AB 11:28 PM PCB Development: RE: I2C pull-up resistor on mitySOM 5CSE-H4-3YA-RI
- I2C0 is used on the module and cannot be used on a carrier board, it does have the necessary pull ups on it.
I2C2 or 3 do not have pull ups installed on the module. Note that I2C2 can only be accessed if routes through the FPGA fabric... - PC 11:09 PM PCB Development: RE: I2C pull-up resistor on mitySOM 5CSE-H4-3YA-RI
- Yes, those are the pins I am talking about. Thanks!
For future reference, do I2C2, I2C3, and I2C0 signals have built-in pull-up resistors? - AB 10:17 PM PCB Development: RE: I2C pull-up resistor on mitySOM 5CSE-H4-3YA-RI
- Pablo,
If you are asking about the "I2C1" signals at pins 28 and 30 of the module there are no pull-ups on the module. You would need to place 2.2k pull-ups to 3.3V on your carrier board for those signals if used as I2C.
If those a...
Does the mitySOM 5CSE-H4-3YA-RI have built-in pull-up resistors in the I2C pins?
The manual does not mention anything specific to pull-up resistors in the I2C pins.
Thank you for reading.
