Change to retry setting up I2C command rather than waiting indefinitely

[lonerzzz]

With a large I2C bus, I encountered a situation where the following line in esp32-hal-i2c.c, method i2cInitFix hung indefinitely.

while(!i2c->dev->command[2].done);

Adding the included changes resolved the problem in my situation, by allowing a retry.

Can we please have this tested with a few devices? What comes to mind is OLEDs for the big transfer size, EEPROM for holding the SDA while operation is executed and some more general sensors.

I have tested with MCU to MCU communication so far. Will be testing to sensors and with 1K transfers shortly.

I tested this patch and it breaks EEPROM communication for me.

unfortunately i cannot say more about the specific reason, at this point, other then that.

i tested it with one of these cheep RTC / EEPROM modules.

I think it should maybe use some sort of timeout ;) have to see what is the max time that regular eeproms can keep the line LOW though

I have a fix that has proven more stable for handling lockup so I am closing this issue in favor of my newer submission.
