Hello JohnnyBitGoode,

I had no idea someone was working on the LV08 too… I have a modified version of skot’s firmware working on my LV08.

Hello Bonkerz

Yes, I managed to get my LV08 working fully a couple of days ago on v2.5.1-TCH which is forked from skot as well. While the modifications you made to the TPS546.c file communicate to all 3 TPS546 regulators at the same time, it doesn't allow you to query each regulator independently. I went for this approach:

Code:

static i2c_master_dev_handle_t tps546_dev_handle[3]; // For up to 3 TPS546 devices (LV08)
static uint16_t TPS_I2C_ADDR[3] = {0x7F, 0x24, 0x14}; // [1] (0x24) is only referenced for single TPS546 devices

And so I had to add another variable to all the relevant functions:
TPS_IDX = {0, 1, or 2}

Code:

/* public functions */
int TPS546_init(TPS546_CONFIG, int TPS_IDX);
void TPS546_read_mfr_info(uint8_t *, int TPS_IDX);
void TPS546_set_mfr_info(int TPS_IDX);
void TPS546_write_entire_config(int TPS_IDX);
int TPS546_get_frequency(int TPS_IDX);
void TPS546_set_frequency(int, int TPS_IDX);
int TPS546_get_temperature(int TPS_IDX);
float TPS546_get_vin(int TPS_IDX);
float TPS546_get_iout(int TPS_IDX);
float TPS546_get_vout(int TPS_IDX);
void TPS546_set_vout(float volts, int TPS_IDX);
void TPS546_show_voltage_settings(int TPS_IDX);
void TPS546_print_status(int TPS_IDX);

When I need to update the dashboard temperature of the TPS546 devices on the LV08, I query all three but only display the highest temperature. Also power in watts is an accumulation of all 3 TPS546 device's power (voltage * current), with an offset of 18 watts added (6 watts for each regulator). This exactly matches the results I got from the original Lucky Miner v1.0.0 firmware...

Nice work! I like this approach better, I am still trying to implement a similar code to what you have done.

Unfortunately I've just come across an issue that's really bizarre!

Yesterday I received my 4th LV08 and set it up with my details and mined for several hours at 3TH without any problems. Usually I run my miners with the original loaded firmware for a day or so before I open them up, backup the firmware and install my own modded firmware. However, I decided after only a couple of hours to install my modded firmware on this my 4th LV08.

No matter what I've tried, only 6 out of the 9 ASIC chips are mining. I used the same modded esp-miner.bin and www.bin files on this miner as with my other three LV08s but still this 4th LV08 has only 6/9 ASICs working. I have confirmed that all 3 TPS546 regulators are added to the i2c bus and that they have been initialized with the same settings. However, it's the middle voltage regulator that is not supplying power to the middle 3 ASIC chips.

I've even used a full firmware backup (v2.5.1 TCH) from one of my other LV08 miners on this new 4th LV08 but the results are the same, only 6/9 ASICs are mining. When I reinstall the original firmware that I backed up before I installed the updated firmware (luckily), all 9 ASIC chips are mining again!

All four LV08 miners appear identical. Looking at all the serial numbers, my first two LV08s are lower than my 4th LV08. But my 3rd LV08 serial number is higher than my 4th one!

Anyone else experience this issue?
